THIS IS A RUSH TRANSCRIPT. THIS COPY MAY NOT BE IN ITS FINAL FORM AND MAY BE UPDATED.

JAKE TAPPER, CNN: "The Sun and the Moon and The Rolling Stones," a great book. It comes out May 10.

UNIDENTIFIED MALE: Thanks, Jake.

TAPPER: And that is it for "THE LEAD." I'm Jake Tapper, turning you over to Wolf Blitzer in THE SITUATION ROOM. Thanks for watching.

WOLF BLITZER, CNN HOST: Happening now, breaking news. Pulling ahead. Our new national poll shows Republicans are badly divided but united when it comes to expecting Donald Trump to lead the GOP ticket in November. On this, the eve of a critical primary in Indiana, can Trump seal the deal?

Viable path. Ted Cruz goes toe to toe with an angry Trump supporter in Indiana and says he's in the race to the finish, as long as there's still a path to victory.

Not giving up. Bernie Sanders says he has a tough path ahead, but he insists it's not impossible for him to win the Democratic nomination.

And family feud. Prince's relatives gather for a court hearing to determine the fate of his estate and his vault of unreleased music as new questions surface about the pop star's health in the last weeks of his life.

I'm Wolf Blitzer. You're in THE SITUATION ROOM.

ANNOUNCER: This is CNN breaking news.

BLITZER: Breaking news. We're counting down to the Indiana primary. Critical for both Republicans and Democrats, even as our new polls show voters on both sides think they know who would be on the ballot in November.

Donald Trump says the GOP race is all over if he takes Indiana. Fifty-seven Republican delegates are up for grabs there. A quarter of what he still needs to secure a first ballot convention win.

Ted Cruz says the race is closer than it looks. He's been going all out, treating Indiana like a do or die must-win state. But Cruz says he's in the race to the end as long, as there was a viable path to victory. On the Democratic side, Bernie Sanders says he, too, is in the race

all the way, suggesting there will be a contested convention, but Hillary Clinton may already be looking ahead. She's moved on to Kentucky and West Virginia today; and our new CNN/orc poll shows voters are looking ahead, as well. The vast majority of those polls expect Clinton and Donald Trump to be their parties' nominees.

Our correspondents, analysts and guests, they will have full coverage of all of the day's top stories. Let's begin with our senior White House correspondent, Jim Acosta. He's in South Bend, Indiana.

Jim, can Donald Trump close this deal?

JIM ACOSTA, CNN SENIOR WHITE HOUSE CORRESPONDENT: That is the question, Wolf. Donald Trump and his team are making the case that a big win here in Indiana will mean the GOP race is over. A victory for Trump would certainly ramp up the pressure on Ted Cruz to drop out but our new CNN/ORC poll shows that if Trump gets his way, if he becomes the presumptive nominee, he will lead a Republican Party that is deeply divided.

(BEGIN VIDEOTAPE)

DONALD TRUMP (R), PRESIDENTIAL CANDIDATE: Are you going to eat all that?

ACOSTA (voice-over): One day before the Indiana primary, Donald Trump can taste victory.

TRUMP: Indiana is very important, because if I win, that's the end of it. Momentum in the latest polls, the GOP front-runner is heavily favored to win Indiana, an outcome that could deliver a knockout punch to Ted Cruz. Talking to reporters, the Texas senator vowed to hang on.

SEN. TED CRUZ (R-TX), PRESIDENTIAL CANDIDATE: I am in for the distance. as long as we have a viable path to victory, I am competing to the end.

ACOSTA: But even as he campaigns with Indiana's governor, Cruz is struggling to change minds, even sparring with a Trump supporter.

CRUZ: Sir, America is a better country.

UNIDENTIFIED MALE: Without you.

CRUZ: Thank you for those kind sentiments.

ACOSTA: Then telling the crowd to compare his handling of criticism with the clashes at Trump rallies.

CRUZ: If I were Donald Trump, I wouldn't have come over and talked to you. I wouldn't have shown you that respect. In fact, you know what I would have done? I would have told the folks over there, "Go over and punch those guys in the face." That's what Donald does to protesters. ACOSTA: But the latest CNN/ORC poll finds Trump remains the

overwhelming GOP favorite across the country and showed Republicans would be much more dissatisfied with Cruz as their nominee.

Still, our poll notes the GOP is bitterly divided, with nearly half saying the party will not unite.

TRUMP (via phone): She's playing the woman card, and we're right now making a list of many, many times where it's all about her being a woman.

ACOSTA: On CNN's NEW DAY, Trump insisted his party will rally behind him to defeat Hillary Clinton, and he defended his latest inflammatory talk...

TRUMP (on camera): Because we can't continue to allow China to rape our country, and that's what they are doing.

ACOSTA: ... on trade with China.

TRUMP (via phone): Frankly, as far as China is concerned, everyone knows that's true; and it gets the point across.

ACOSTA: And the real-estate tycoon was just as harsh at slamming the demonstrators who violently protested his candidacy in California over the weekend.

TRUMP: And they wear masks, and the police told me these are thugs.

ACOSTA: In Indiana, Trump is counting on having the crowds on his side as he appears with legendary Hoosier basketball coach Bobby Knight, just one of several controversial sports figures to endorse his campaign, from Dennis Rodman to Mike Tyson.

[17:05:10] Cruz is trying to use Tyson's endorsement against Trump, noting the boxer was once convicted of rape.

CRUZ: I don't think rapists are tough guys. I think rapists are cowards and bullies and weaklings.

(END VIDEOTAPE)

ACOSTA: Now, speaking of all these endorsements, Donald Trump is sounding as if Indiana's governor, Mike Pence, is endorsing him and not the candidate he's actually backing, Ted Cruz. Trump noted that Pence has also had good things to say about him over this past weekend.

Either way, Trump is poised to drive Cruz out of any reasonable chance of winning the nomination for the Republican Party and force the "never Trump" movement inside the GOP to start working on a Plan C or a Plan D or whatever it is at this point, Wolf.

BLITZER: Jim Acosta in South Bend, Indiana for us. Thank you. Let's go to our political reporter, Sara Murray. She's in Carmula

(ph), Indiana, right now, where Donald Trump has been speaking. How confident is the Trump campaign, Sara, heading into tomorrow's primary?

SARA MURRAY, CNN POLITICAL CORRESPONDENT: Wolf, Donald Trump has been very confident at this campaign, and he once again reiterated this idea that if he wins Indiana, it is over. But then he took it a step further and said, "Even if I don't win Indiana, I'll win the week after that. Maybe the week after that." A sentiment that's running through the Trump campaign, this idea that no matter what happens in Indiana, even though they feel confident here, they're going to get to 1,237 before they get to Cleveland. That's what Trump believes, and that's clearly what his advisers believe, as well, Wolf.

BLITZER: Is there sense out there, Sara, that that sort of short- lived controversial Cruz/Kasich alliance may actually have backfired and wound up helping Donald Trump?

MURRAY: Well, they haven't done a great job messaging it, have they? Ted Cruz saying it wasn't an alliance, and John Kasich saying his supporters should vote for him anyway in Indiana.

But now we're seeing some polling with NBC News, "Wall Street Journal" there that says 58 percent of the Indiana Republican primary voters don't approve of this.

And we are hearing a little bit of sentiment from the Kasich camp that there is some buyers' remorse.

Meanwhile, the Cruz camp still believes that this is a good deal for them. They think it puts them head to head against Donald Trump and gives them the best shot they can at taking him down. But as you heard Jim Acosta talking about, it is going to be an uphill climb for Ted Cruz here in the Hoosier state -- Wolf.

BLITZER: Certainly. All right, Sara, thanks very much.

Sara Murray reporting for us.

Joining us now, Republican Congressman Adam Kinzinger of Illinois.

Congressman, thanks very much for joining us.

REP. ADAM KINZINGER (R), ILLINOIS: Hey, Wolf. Good to be with you.

BLITZER: So if Donald Trump wins tomorrow in Indiana, is he the presumptive nominee?

KINZINGER: Yes. It's really hard to see how he's not. I guess Cruz could maybe run just about every other race or every other win of the coming states and maybe be the nominee. But this is definitely a big deal for Trump if he wins tomorrow, because this was considered a Cruz strong territory.

So there's no doubt a victory for him will do a lot to seal him as the nominee. If he loses, this continues down the road, and from what I've heard there's, you know, polling's all over the place. We have some of the public polling, but I've heard that there's some private polling showing it's actually a lot closer. So these are all turnout games, and it will be fun to watch tomorrow.

BLITZER: Because you saw that "Wall Street Journal"/NBC/Marist poll, which shows Trump in Indiana way ahead. He does have a lot more votes. In all the 40 contests so far, primaries, caucuses, about 2.3 million more votes than Cruz.

I guess -- there you see the number on the screen. He's got more than 10 million. Cruz has 6.8 million. Kasich down to 3.6 million. If it is a contested convention, a lot of people, a lot of Republicans are going to be pretty angry, since -- since Trump clearly has millions more votes.

KINZINGER: Yes. And you know, if they're angry, they probably have a right to be. The reality, though, is this is how it's done. This is how it's been done for many, many years.

And if we go to a contested convention, you know, Donald Trump will have to work hard to win -- to win over the delegates, to work on a second and a third ballot strategy. They knew that this was how this works from the very beginning.

Now that they're caught flat-footed, they're, you know, kind of throwing out a lot of -- they're upset and sad. But yes, people will be upset. They probably have every right to be. But this is how it's done. Now, if we want to revisit how we nominate candidates in the next cycle, that's probably a conversation that will be welcomed.

BLITZER: You'll have four years to come up, to come up with some new ideas if you want to do that. Let's talk about -- let's say he loses tomorrow, Cruz, in Indiana. He says he's in it for the distance if there's a viable path for him.

Kasich says he's still in it, as well, even though he's got an even more difficult path than Cruz does. But for all practical purposes, if he loses tomorrow, will you be on board with Donald Trump?

KINZINGER: No, I'm not there. You know, look, I probably will definitely not support him until at least the convention. And I have a hard time seeing how I ever get to "yes" on Donald Trump.

I'm not a "never Trump" guy. But I'm definitely somebody who puts my party above my party, and in my view, what I've heard him say on foreign policy, what I've heard him say, he's going to eliminate the debt but not touch Social Security, as not having real conversations with the American people, that frankly, my party has spent a lot of time trying to say, "Hey, look, here's the harsh realities of where we're facing, and these are a way out."

[17:10:20] So leadership to me is not just about reflecting people's anger, just -- and not just about holding up their insecurities. It's about showing people a way out. And so I'm not there with Trump yet. Look, if he changes his tone and

starts to have some good solutions, I could get there. But as of today, I'm not.

BLITZER: Ted Cruz wouldn't say if he'd back Trump in November if he's the Republican presidential nominee. So I guess what's going to happen to the party? Let's say Trump is the nominee. How divided will the Republicans be, looking ahead, let's say, to a Hillary Clinton general election campaign?

KINZINGER: Well, the great unifier is Hillary Clinton for Republicans, so that will definitely work in unity's favor. But I think the question really is going to be for Donald Trump to answer. You know, is he going to change his tone from one of division, one of kind of complaining, you know, whining when things don't go his way? Is he going to change it to talking about, you know, really what it is that our party believes in and where he wants to take this country, with some detailed explanations, not just -- not just kind of populist rhetoric?

He can unite this party, but it's going to take a major change and a major shift from how he's been so far. You know, look, I don't put it past him to be able to do that. I hope he can. But I kept thinking he was going to pivot to much more mature conversation months ago when he hasn't yet.

BLITZER: Whatever your Republican colleagues in the house, Representative David Jolly of Florida, said today he doesn't know if he'd vote for Trump or Hillary Clinton in November. Under no circumstances, I take it, would you vote for Hillary Clinton against Donald Trump?

KINZINGER: No. I'm not going to vote for Hillary Clinton and, like I said, I hope I can get to yes on Trump. But if I don't, I would intend to -- you know, you can always write somebody in or leave it blank and vote down ballot. It's the right -- you know, my right as a private American to make that decision.

But no, I don't -- I wouldn't support Hillary Clinton. That's for sure. It would be another four years of the last eight years, which we've seen, which I don't want.

But I hope Trump can come around. We've got to see some real change, though.

BLITZER: Any chance you think Paul Ryan will come around?

KINZINGER: I don't think so. No. I think he's made it pretty clear. I'd love to see a Paul Ryan as president, but I think that's probably not in the cards for 2016.

BLITZER: Yes, you might have to wait four years or eight years. He's still a young guy, so you've got plenty of time to work with him on that.

Stand by, Congressman. We have much more to discuss. We're going to take a quick break. We'll be right back.

(COMMERCIAL BREAK)

[17:16:53] BLITZER: As we count down to the critical Indiana primary, we're back with Republican Congressman Adam Kinzinger of Illinois. He's a U.S. Air Force veteran who served in both Iraq and Afghanistan.

Congressman, Senator Lindsey Graham is predicting another 9/11 if Donald Trump is elected president. Do you think the U.S. will be vulnerable to more attacks like 9/11 if Trump is president?

KINZINGER: I don't know. That's a tough one to answer. Look, I think he needs to change -- I think saying things like "banning all Muslims" is actually really putting -- it's dangerous. It may work for politics domestically, but it's dangerous. Because you look, for instance, at Yemen.

The Saudis just recently dealt a huge blow to al Qaeda in the Arabian Peninsula, which, you know, are a very bad strain of al Qaeda. You have the Saudis pushing back, the Iranians. You have the Jordanians and other allied regimes engaged against ISIS.

To just make blanket statements like that begins to alienate the allies that we need to actually win these wars. So I'm not going to go as far as to say another 9/11 because of Donald Trump, but I will say rhetoric has meaning and it has an impact. And I heard that when I got back from the Middle East few weeks ago. I've heard that from everybody we've met with.

BLITZER: ISIS is claiming responsibility for a Baghdad car bombing, killing at least 16 people, injuring 43 others. This is more than a decade right after the U.S. spent literally more than a trillion dollars, hundreds of billions of dollars to try to develop a stable regime there, a stable country in Iraq, a secure military. For all practical purposes right now, has Iraq essentially become Syria?

KINZINGER: No, no. Look, I think they're -- they're in the process of still developing self-governance.

We had Iraq in a pretty good place in 2011 and, in fact, President Obama himself said, you know, when the last troops left that we're leaving behind a stable Iraq. We were there. We were able to help the different sectarian interests have a dialogue and feel like they're empowered.

Unfortunately, when we left a lot of that under -- under al-Maliki started to fall apart. And so there's going to be a lot of rebuilding to do.

But this isn't Syria. First off, we don't have a brutal dictator who's killed a half a million people. Secondly, you do have ISIS, but you have a national army that, as effective as they have been in the past, is refocused on retaking territory. You don't have that in Syria. You have a nationalist army that's focused on killing innocent civilians. But look, if we're not careful, if we disengage with Iraq, it could be

another Syria and, frankly, you have the same -- you have the same concerns in Libya as we're seeing in Egypt, eventually.

BLITZER: It looks like a disaster, though, in Iraq right now. Baghdad is the largest city. The Green Zone was invaded over the weekend. That's the secure area where American diplomats, the U.S. Embassy and the other foreign embassies are there. The protesters got out, but still, they moved into the Green Zone.

And the second largest city in Iraq, Mosul, a city of 2 million people, now for two years has been controlled by ISIS, and the Iraqi military has done nothing so far to try to retake the second largest city in -- why do you think it's not as bad as Syria?

KINZINGER: Well, it's certainly a depressing area. That's for sure. You see as the Iraqis right now with, frankly, U.S. leadership -- it's essential in this -- are preparing, I wish it was a year ago, but they're preparing to eventually take back Mosul. Keep in mind, it's two million people. That's a huge operation.

The protests in Baghdad were not necessarily ISIS-inspired. These were from al Sadr and these are people that feel disaffected by the national government. The president of Iraq is trying to bring people together again, and you have a lot of entrenched interests there that like the old system of doing business, the kickbacks, the contracts and everything else.

So -- and then, you know, look, a car bomb, as tragic as it is in Baghdad, this is what ISIS wants. They want to do a car bomb in Baghdad and the whole thing is falling apart.

Well, Baghdad is not as bad as it was in the past. There's still a lot more to do, but this is far from Syria. Syria is the incubator of ISIS. Bashar al-Assad has created ISIS by his brutal tactics, by creating areas of non-governance. And Iraq gives us an opportunity, as tough and as bad as it is, to push them out and deal a huge defeat.

BLITZER: Here's the issue in Syria right now, Congressman. You know this well. You've been to the region. You served in the U.S. military, both Iraq, and you served in Afghanistan, as well.

In Syria right now, at least 300,000, maybe 400,000 people have been killed over the last four years. Millions of people have been made into refugees, homeless domestically. They've been displayed across borders.

But the fear right now with the collapse of what supposedly was a cease-fire, the bad situation, a horrendous situation in Syria right now potentially could get a whole lot worse. Do you believe that?

KINZINGER: Yes, absolutely. I think this could get worse. This could spread to other areas, you know, frankly, Jordan, not Lebanon, Libya. It already has spread, I would argue. I think that's why you're seeing a lot of the instability in the Middle East. The other big issue is this. You have a whole generation of children

right now that are not going to school. I was in Turkey at a refugee camp, and the Turks are doing a really good job of trying to do what they can to educate these children, because when kids don't learn how to read or write, when they don't learn about the bigger world outside of themselves, they're fertile ground for terrorist groups like ISIS or the next generation of ISIS to come along and recruit from.

So education is extremely important. When you have failed states, kids aren't being educated; families are being torn apart. And it leads to a lot of resentment.

This is a long -- this is a generational fight. This is going to be going on for a long time. Hopefully not in Syria, but this fight in general. We have to think long term. Kids that are going to school and learning how to read and write.

BLITZER: Yew, what worries me a lot, and I'm sure it worries you, as well, that in Syria, ISIS controls some cities, mid-size cities like Raqqah, their capital, a few hundred thousand people. But in Iraq, they control Mosul, a city of two million people for two years now, and the Iraqi military so far has done nothing to recapture, to liberate that city. It's a worrisome sight.

All right, Congressman, thanks very much for joining us.

KINZINGER: You bet, Wolf. Take care.

BLITZER: Coming up, our brand-new CNN poll shows Republican voters fully expect Donald Trump to be their party's nominee. On this, the eve of a crucial primary, can he close the deal?

And amid new questions about Prince's health in the last weeks of his life, the pop star's relatives gather for a court hearing to determine the fate of his estate and his vault of unreleased music.

Stay with us. You're in THE SITUATION ROOM.

(COMMERCIAL BREAK)

[17:28:04] BLITZER: As we count down to the Indiana primary, let's bring in our experts. Joining us, our CNN political director, David Chalian; Rebecca Berg, the national political reporter for Real Clear Politics; and our CNN political commentator, Ana Navarro. Guys, thanks very much for joining us.

David, look at the new CNN poll just released, just coming out right now. Trump's national support clearly growing. Cruz losing support nationally.

CNN also asked Republican voters if the party can be united. Here's what they say going forward in November. Right now, seven percent said they're united, divided but will unite going forward after the contest is -- the Republican nomination is determined. Divided, will not unite, almost 50 percent, 49 minute. What does that say to you? DAVID CHALIAN, CNN POLITICAL DIRECTOR: That's says that that's a

pretty big to-do on Trump's list when he does, indeed wrap this nomination up. It's ticking up a little bit from where it was.

And remember, this is what Republicans are saying about their own party. This isn't Democrats coming up with these numbers. Forty-nine percent of Republicans believe they still will not be united in November. That is a problem.

Now, we've all seen tough nomination fights, and partisans do tend to come home. Certainly, that will happen here, too. We usually don't see division quite this large.

BLITZER: We saw that happen in 2008. Hillary Clinton was defeated by then-Senator Barack Obama. A lot of division within the Democratic Party. But they united, and he was elected. Twice, in fact.

Ana, how critical is tomorrow, Indiana, for Ted Cruz?

ANA NAVARRO, CNN POLITICAL COMMENTATOR: I think it's hugely critical. In politics the expectations game is very important. And the expectation here that he built, in a way, was that he was going to win Indiana, that Indiana was his firewall.

So if it turns out not to be his firewall, it's going to be a real problem for him. He's had a tough week, frankly. I think he's been very hurt by there being no debates. He's lost that platform, where 20 million people, 25 million people can watch him at one time. He's had to create media events.

The events he created last week, they didn't go off all that well. The endorsement from Governor Pence wasn't exactly made-for-TV. The bump he hoped to get from the Carly Fiorina as V.P. announcement fell with more of a thump than a bump. And, you know, he's had a tough, tough week.

[17:30:18] If he wins, it's going to be a huge victory. Because at this point, we know he's on the ropes. If he loses, he's going to have a very big problem tomorrow night.

BLITZER: But he says if he loses, he's still in it for the distance, he says, if there's a viable path. If he loses Indiana, is there a viable path for him?

BERG: Well, that's a great question. And I think after we see the results from Ted Cruz and his campaign are going to have to do some hard math and take a look at the numbers, because if, indeed, as the polling has suggested, Donald Trump will win in Indiana and win, potentially, by a lot, if he even sweeps the delegates there, which is one potential outcome at this point, I think Ted Cruz is going to have a tough case to make that he can do better in California.

And certainly, John Kasich is not really pulling his weigh in Oregon and New Mexico. Washington is going to be a very tough state for these guys, as well. Where do you win moving forward? I mean, Ted Cruz could win in Nebraska, maybe. You have a Rickets as the governor there, and that family has been very anti-Trump. But it wouldn't be enough to stop him from reaching 1,237, potentially. And so his team is going to have to look at the numbers and say, "Is this possible?" Ted Cruz is not going to stick around in this race if there's not a possibility.

BLITZER: Nebraska, the week after.

CHALIAN: Donald Trump can't get to 1,237 until June 7, and so define viable. Right? Anybody -- in Ted Cruz's eyes, he may feel that, since Trump is not going to cross that magic number and cross that threshold of the delegates needed to secure the nomination until as early as June 7, does Trump stick -- does Cruz stick around in some way, just in case Trump implodes or trips up?

BLITZER: Hypothetically, let's say it goes to a contested convention, Trump doesn't have the 1,237 on the first round. Cruz, maybe Kasich, they're still in it. Here's the question: Can Trump win on a second round?

CHALIAN: It's going to be tougher for him. There's no doubt about it, because 95 percent of the delegates are bound by the primary caucus results on that first ballot. But then something like 40 percent of the delegates are bound on the second ballot. So he clearly will lose some support, if you just have been tracking what our team at CNN Politics has been doing nonstop with these delegate events. Clearly, Cruz has built some support, some added support for a potential second ballot that Trump has not. So it becomes a much tougher road.

BERG: But there is this question of what happens if Donald Trump is very close to 1,237? What if he's at 1,210? Then, could the delegates at the convention have a case to make to deny him the nomination? It would be a very hard sell.

BLITZER: He's already over 1,000.

Very quickly, Ana, Donald Trump, he told CNN that he thinks Bernie Sanders, at least some Bernie Sanders supporters, will back them because of his views on trade, because he claims Hillary Clinton has treated Bernie Sanders' followers, in his words, "unbelievably badly." Do you think that's at all realistic that Trump can attract some of the Bernie Sanders supporters?

NAVARRO: Let me tell you, Wolf, you know, that statement sounds absolute crazy on its face. But if you start digging in a little bit, digging, you know, through what he's saying, there is some logic to what he is saying.

I'll tell you, one of the big surprises for me, in places like Iowa and New Hampshire, was looking at people and speaking to people at Bernie Sanders' rallies who will tell you that their second choice was Donald Trump, not Hillary Clinton. I do think there is some overlap between Trump and Sanders supporters. They're looking for an outsider. They're looking for a disrupter. They're looking for somebody that they see as anti-establishment. Now, he's going to have to work hard to court them. And I've also learned in the last 10-11 months, do not underestimate

Donald Trump. Do not overestimate Hillary Clinton. If you do so, you do so at your detriment.

BLITZER: Good point. All right, guys, stand by. There's more politics coming up.

Also coming up, a CNN exclusive. President Obama revealing new details about what it was like watching the high-stakes raid on Osama bin Laden's compound.

And later, inside details about the increasingly bitter family feud over Prince's estate.

(COMMERCIAL BREAK)

[17:38:48] BLITZER: Senator Bernie Sanders is making a bold prediction. He says the Democrats are heading for a contested convention. Whatever happens, CNN's new nationwide poll shows most Democrats think Hillary Clinton will end up with the nomination.

Our national correspondent, Suzanne Malveaux, is joining us now. Suzanne, Sanders isn't showing any signs of giving up, is he?

SUZANNE MALVEAUX, CNN NATIONAL CORRESPONDENT: Absolutely not, Wolf. I mean, the belief is inside the Sanders team is that everybody should get their opportunity to vote as the primaries continue. So Sanders has the money and the momentum to go to July, and that is exactly what they are planning on doing.

(BEGIN VIDEOTAPE)

MALVEAUX (voice-over): Barnstorming Indiana tonight, Bernie Sanders is taking a page from Donald Trump's playbook, blasting the Democratic primary process.

SEN. BERNIE SANDERS (I-VT), DEMOCRATIC PRESIDENTIAL CANDIDATE: When we talk about a rigged system, it's also important to understand how the Democratic convention works.

MALVEAUX: Sanders sharply criticizing the influence of super delegates.

SANDERS: It's the way the system works, is you have establishment candidates who win virtually all of the super delegates. It makes it hard for insurgent candidacies like ours to win.

MALVEAUX: Sanders faces a steep deficit in total delegates and is trailing Clinton by eight points in a new CNN/ORC national poll. He's looking to regain some momentum with a win in the Hoosier state Tuesday.

[17:40:08] SANDERS: We're going to fight for every last vote.

MALVEAUX: Indiana polls show a tight race, with Clinton holding a four-point lead in a new "Wall Street Journal"/NBC/Marist survey. SANDERS: I'm trying to say, look, "I'm going to tell you what I'm

going to do so you can hold me accountable."

MALVEAUX: Hillary Clinton campaigning today in Kentucky, which holds its primary later this month, talking up her plan to revitalize coal country.

CLINTON: Appalachia coal has taken a huge hit and, you know, it's something that I am really worried about.

MALVEAUX: Clinton's remarks coming on the heels of these comments during a CNN town hall in March.

CLINTON: I'm the only candidate which has a policy about how to bring economic opportunity, using clean, renewable energy as the key, into coal country; because we're going to put a lot of coal miners and coal companies out of business.

MALVEAUX: Today, Clinton said she'll put her husband in charge of the effort to bring back Appalachian communities.

CLINTON: I told my husband he's got to come out of retirement and be in charge of this. You know, he's got more ideas the minute than anybody I know.

MALVEAUX: With Clinton closing in on the Democratic nomination, she's looking more and more toward the general election and Republican front-runner Donald Trump.

CLINTON: We cannot let Barack Obama's legacy fall into Donald Trump's hands.

MALVEAUX: Another sign the Democratic momentum has shifted, Clinton out-fundraised Sanders, if just barely, for the month of April, the first time this year her campaign has bested Sanders in any month.

President Obama used Sanders' favorite fundraising talking point...

SANDERS: Our average contribution is $27.

MALVEAUX: ... to inject some levity in the campaign during his speech at Saturday's White House Correspondents' Dinner.

BARACK OBAMA, PRESIDENT OF THE UNITED STATES: Bernie, you look like a million bucks. Or to put it in terms you'll understand, you look like 37,000 donations of $27 each.

MALVEAUX: And poked fun at Clinton's struggle to appeal to younger voters.

OBAMA: Hillary trying to appeal to young voters is a little bit like your relative who just signed up for Facebook. "Dear America, did you get my poke? Is it appearing on your wall?"

(END VIDEOTAPE) MALVEAUX: Clinton seems focused on how to win in historical swing

states that have gone either way in the last four cycles of the general election, So we're talking about North Carolina, Florida, Ohio, New Mexico and many others. They're looking at those policies that have impacted the key demographics in those states to figure out how to shore up their support -- Wolf.

BLITZER: A good point, Suzanne. Thank you.

Coming up, new details emerging right now about Prince's health problems and the fight for his estate.

Also, a CNN exclusive. President Obama in the White House situation room looking back on the raid that killed Osama bin Laden.

(COMMERCIAL BREAK)

[17:47:00] WOLF BLITZER, CNN ANCHOR: Now a CNN exclusive, President Obama revealing new details about what it was like to watch the U.S. special forces raid that killed Osama bin Laden. For the fifth anniversary of the raid, CNN's national security analyst Peter Bergen met with the president in the White House situation room.

(BEGIN VIDEOTAPE)

BARACK OBAMA, PRESIDENT OF THE UNITED STATES: Well, we came in here at the point where the helicopters were about to actually land. It's here where we observed, for example, that one of the helicopters got damaged in the landing.

PETER BERGEN, CNN NATIONAL SECURITY ANALYST: And what were you thinking?

OBAMA: I was thinking that this is not an ideal start.

(LAUGHTER)

OBAMA: Look, we were all worried. The good news was it didn't crash. Our guys were able to extract themselves. The bad news was that the helicopter itself had been damaged and this is an example, though, of the kind of meticulous planning that had been done. Even though we had the best helicopter operators imaginable, despite the fact that they had practice these landings repeatedly in a mock-up, we couldn't account for temperature and the fact that helicopters start reacting differently in an enclosed compound where heat may be rising.

(END VIDEO CLIP)

BLITZER: Peter's exclusive interview is featured in the CNN special report that airs later tonight.

Peter is joining us now in our SITUATION ROOM. Peter is also the author of the new and very important book, "The United States of Jihad." There you see the cover right there.

Peter, you wrote the book on the manhunt for bin Laden but now five years later you sat down with President Obama and several of his key advisers. You learned new information. Share some of that with us.

BERGEN: Well, he was leaning towards the raid relatively early on and he sort of held back on making a decision because, you know, he didn't have to make the decision immediately. So that -- I found that interesting.

We also spoke at considerable length with (INAUDIBLE) McCraven who's the architect of the raid, who, you know, both you spoke to in Aspen when he was still in uniform shortly after the raid, now obviously he's retired and, you know, he's able to speak at greater length. And, you know, he really narrated for us the planning of the raid from his perspective and the execution of the raid from his perspective, which I think is -- you know, I think viewers will find that a very interesting part of the story.

BLITZER: Bin laden was living for years in Abbottabad right outside the Pakistani equivalent of a West Point, a major military facility there.

[17:50:03] Did top Pakistani officials know he was living in their country?

BERGEN: We asked that question to President Obama who said there's no evidence for that. We also asked CIA director John Brennan and the director of national intelligence, Jim Clapper. They also said there's no evidence for that. Interestingly, former Secretary of State Hillary Clinton, who was secretary of state as you recall during this operation, she says that she thinks the Pakistanis knew. She didn't offer evidence for that, but she does point to not only what you just said, Wolf, which is that he was living near a Pakistani military academy, also that this town, this city is a place where quite a number of Pakistani military officers go to retire. And she felt that, you know, somebody in the military perhaps retired knew something.

BLITZER: Interesting stuff. And I know there's a lot more coming up later tonight, Peter. Thank you so much for doing this.

And to our viewers, you're going to see much more of Peter Bergen's exclusive interview with the president and his top national security team, later tonight. Please tune in 8:00 p.m. Eastern for a CNN exclusive report "WE GOT HIM." It airs on "AC 360" starting at 8:00 p.m. Eastern.

We also have new details about Prince's health problems before his unexpected death. This comes as we're following an increasingly tense dispute over his estate.

Our Brian Todd has the latest now. He's joining us.

Brian, you learned about some heated exchanges between family members?

BRIAN TODD, CNN CORRESPONDENT: Right, Wolf. We're told from sources tonight that the siblings, Prince's siblings were shouting at each other during their initial meeting over how to divide his estate. He's got five half siblings and one full sibling battling it out over this because apparently he had no will.

There's about $300 million at stake here, including possibly hundreds of unreleased songs in a mysterious vault.

(BEGIN VIDEOTAPE)

TODD (voice-over): Prince's only full sibling, Tyga Nelson, arrives in court for hearings over the pop star's $300 million estate. Proceedings which have already gotten very messy. A source with firsthand knowledge of the discussions telling CNN the initial meeting between Prince's siblings was contentious and ended in shouting.

Today, Tyga Nelson was on one side of the courtroom, lawyers for Prince's half siblings were on the other. Making this potentially more contentious, his sister claims Prince did not have a will.

Tyga Nelson is maneuvering with five half siblings of Prince over how to divide the estate. One of them claims the singer had a vault at Paisley Park.

ALFRED JACKSON, PRICE'S HALF BROTHER: We have seen the vault door, but we never entered.

TODD: There are conflicting reports tonight as to whether that vault has been opened yet. A lawyer for Prince's half brother denies it. It's rumored to have enough of Prince's unreleased music to put out one album a year for the rest of the century. Prince's half brother says he wants to release it.

JACKSON: To let people know how great he really is.

TODD: But it's now up to a special administrator. Four years ago, Prince made what now seems like an eerie remark about his unreleased songs in an interview with ABC's "The View."

PRINCE, MUSICIAN: One day someone will release them. I don't know that I'll get to release them.

TODD: Meantime tonight, Prince's personal chef says during the last weeks of his life, the star had lost his appetite, that he ate less, and drank less water.

Ray Roberts told the Associated Press, quote, "It felt like he wasn't himself probably the last month or two. I think he was just struggling with being sick a lot."

Robert says that was unlike the healthy vegan he knew who loved roasted beats and minestrone soup. The mystery surrounding Prince's death plays out against the backdrop of a seemingly ugly family dispute.

ALEX TANOUYE, TRUST AND ESTATE LAWYER: A sudden windfall can make people do things that they might not otherwise do. I think grieving has a big effect on it. Emotionally people are surprised particularly when somebody famous dies young. They might not have had a chance to say whatever they wanted to say. They may now be forced to sit in a room with people they don't like.

(END VIDEOTAPE)

TODD: Prince's half brother, Alfred Jackson, says he and Prince have lost touch with one another and Jackson told CNN he found out about the singer's death the same way the public found out. Jackson says he was hurt when he wasn't invited to the private memorial to say good- bye to his younger brother -- Wolf.

BLITZER: Brian, you've been speaking to attorneys. How difficult will it be to determine who gets what in that estate?

TODD: Very difficult, Wolf. And we're not talking about just the money. You know, you can divide up the money pretty well with six siblings, and that will be done with that. But with no will at play here it's going to be especially difficult to decide who gets things like Prince's favorite guitars, the rights to "Purple Rain," things like that.

And, Wolf, the family is going to be just slammed with estate taxes. One attorney told us the IRS is going to get 40 percent of everything over $5.45 million, including the value of the music in that vault. They're going to get a lot here, but they're going to have to pay a lot in estate taxes.

[17:55:01] BLITZER: Millions and millions of dollars. All right, thanks very much, Brian, for that.

Coming up, our new national poll shows Republicans are badly divided, but united when it comes to expecting Donald Trump to be their nominee. With a critical primary looming, can Donald Trump now close the deal?

(COMMERCIAL BREAK)

BLITZER: Happening now. Breaking news. Trump Towers. A new CNN poll just released showing a vast majority believe Donald Trump will be the Republican nominee for president, but is the sense of inevitability boosting his support inside the GOP?

Critical contest. Tomorrow's Indiana primary possibly the last chance for Ted Cruz to block Trump from clinching the nomination outright. The Cruz campaign increasingly anxious about his prospects even with a contested convention. Is there a viable path to the --
