officer from legally abiding, and saying i'm required to use only the amount of force necessary to actually stop the force against me. >> well, as i said, two investigations under way. we'll see how this plays out. laura coates, tom fun tess, thank you very much for that. thank you for watching. wolf starts now. hello, i'm wolf blitzer. it's 1:00 p.m. here in new york, 7:00 p.m. in brussels, belgium. 8:00 p.m. in iraq. wherever you're watching from around the world, thanks very much for joining us. we start with a democratic race for president of the united states. and a strategy difference today emerging. hillary clinton took to the streets of new york city. she's in the bronx, talking with voters, riding the subway. as she prepares for the april 19th primary here in new york state. bernie sanders, he's in pennsylvania. he's talking with labor leaders of philadelphia, the pennsylvania primary is april 26th. one week after new york.

sanders changed the narrative of the campaigns today with attacks against hillary clinton last night. listen to this. >> she has been saying lately that she thinks that i am, quote, unquote, not qualified to be president. i don't think that you are qualified if you get $15 million from wall street through your super pac. i don't think you are qualified if you have voted for the disastrous war in iraq. >> i understand bernie sanders thinks you're not qualified? >> well, it's kind of a silly thing to say. but i'm going to trust the voters of new york. >> the more contentious tone also evident in this twitter battle over guns. sanders said only one gun democrat takes gun lobby money to fund her campaign. and hillary saying only one democratic candidate has voted for the nra's most important piece of legislation in 20 years.

you. why is it getting so nasty? it may be because sanders has won 7 of the last 8 contests and tightened the delegate gap. here's what's left. 1,661 pledges out there, more than 200 up for grabs in the new york state primary. that's coming up. the bitter back and forth has certainly escalated quickly in the wake of bernie sanders' double digit win, 13-point win in wisconsin this week. he was asked about his qualifications comments during a campaign stop in philadelphia earlier this morning. >> this is not the type of politics that i want to get. you know what the media loves. it is not the type of politics i want to get in. but let me also be very clear. if secretary clinton thinks that i just come from a small state of vermont, we're not used to this. we'll get used to it fast. i'm not going to get beaten up. i'm not going to get lied about. we will fight back. i would hope we can get away from this. i do have respect for secretary clinton. i don't know who in her campaign

comes up with these brilliant ideas. all i'm saying is, i'm not going to go into new york -- i know they are getting nervous. they lost 7 out of the last 8 caucuses and primaries and every day develop a new approach to the campaign. i gather their approach is -- again, this is a quote from cnn. quote, disqualifying him, defeat him and unify the party later. that sounds to me like they're ready to run a very negative campaign. >> joining us now is brian fallon, press secretary for the hillary clinton campaign. brian, thanks very much for coming in. is this campaign about to get a whole lot more negative? >> i hope not, wolf. we're running the same type of campaign we have from the very beginning. what we've seen in the last few days is the sanders campaign has gone on the attack, and they're using completely false premises to do so. senator sanders you heard in that clip there is trying to play the victim. he's introduced new lines of attack against hillary clinton in the last couple days that are based on completely false premises. first he said that hillary clinton said he wasn't qualified

to be president. she absolutely did not say that. she gave an interview yesterday where despite three followup questions, she deliberately avoided saying that. >> but she also didn't say in that interview with joe scarborough on mortgage. she also didn't say he was qualified. she didn't say he wasn't qualified. but she didn't say he was qualified. >> so this morning she said absolutely senator sanders, i'll take him any day over donald trump and ted cruz. and joe score borrow this morning said i tried my best to get her to say he was unqualified and i couldn't succeed. the "washington post" fact checker today gave bernie sanders three pinocchios. and last night, that's what he did to her. secondly, he has suggested that she has tried to make politics out of the attack at sandy hook. suggesting it was she who called on him to apologize for his vote in favor of gun manufacturer liability. the reality is, he made his comments doubling down to the new york daily news last week in support of that vote he took. and it was the loved ones of the victims at sandy hook that spoke out and said, they wanted an

apology from senator sanders, because they are trying to bring a lawsuit and he's opposing them getting their day in court. that wasn't hillary clinton that called him out on that. that was the victims of sandy hook. >> he says she's not qualified to be president of the united states. because she voted for the iraq war. because she takes all this money from wall street. and that's -- and she supports all these trade agreements that have cost a lot of jobs in the united states. and i want you to respond directly, because he says she should apologize for all of that. >> by those metrics, by those standards, president barack obama is unqualified to hold the office that he now sits in. john kerry, the democratic party nominee in 2004 would be unqualified by that standard. this is an absurd line of attack. and it's probably the lowest we have sunk here in terms of the rhetoric on the democratic side. obviously, to date you've seen us keep it on the level, policy oriented. especially compared to the republicans. senator sanders, though, in the last few days has really stepped away from that. you've seen harsh rhetoric, not

just from the candidate himself, but his campaign manager going around, suggesting this morning that hillary clinton has made a deal with the devil. there's been a coarsening of rhetoric from the sanders campaign that is going to impair our ability to unify the party in the weeks ahead. >> does she take money from the nra lobe, the national rifle association? >> that's another ridiculous attack. there is no question where hillary clinton stands when it comes to gun safety issues. she has opposed the nra at every turn. it's senator sanders that voted consistently with the nra, five times against the brady bill. voted in favor of giving immunity to gun manufacturers, which the gun lobby called the most important vote for them in decades. he voted alongside their interest in that case. that is why the victims of sandy hook have called for an apology. this is another one of those false attacks, similar to when he accused her of taking money from oil and gas companies, which was another thing fact-checked by multiple independent authorities. the sanders campaign is getting increasingly desperate, flailing, because in spite of the recent victories they've had, the delegate math remains

daunting. they should be focused on trying to win support here in new york. new york is a must-win for them. do or die for the sanders campaign in new york. >> why do you say die or die in new york? he has won last seven of the eight last contests. >> the size of our delegate lead now is well above 200. in order to erode that delegate lead, he needs to win and win big. and the four biggest contests left. the first is new york. some 200-plus delegates at stake in new york. that is one of the best last best opportunities for him to eat into the lead we have. if he can't do it new york, no basis to think he can do in california. we'll know in april if sanders has run out of scenarios. we thinkel it be ooh clear hillary clinton been the nominee based on new york and pennsylvania on the 26th. senator sanders should be working on trying to win support here in new york. if he tries to go on the attack against hillary clinton, i think

it will back fire on him. >> that's coming up pretty soon. we have a debit coming up a week from today. between hillary clinton and bernie sanders in brooklyn. thanks very much, brian fallon, for joining us. coming up, we'll hear from the bernie sanders' campaign. get a very different perspective. how they're defending his comments that hillary clinton is not qualified to be president of the united states. and their strategy for new york when she's ahead here in the polls. plus, the brand-new video of one of the suspected airport bombers in brussels, making his get-away. what it reveals, and the piece of evidence police say is still out there.

the race for democratic -- the democratic presidential nomination has reached a new pitch. some would say a fever pitch. senator bernie sanders today strongly defended his criticism that hillary clinton is not qualified to be president of the united states. >> so when you have headlines from the "washington post" quote clinton questions whether sanders is qualified to be president, my response is, well, if you want to question my qualifications, let me suggest this. maybe the american people might wonder about your qualifications, madam secretary, when you voted for the war in iraq, the most disastrous foreign policy blunder in the

modern history america. >> jeff weaver is bernie sanders' campaign manager. joining us now live from burlington, vermont. jeff, thanks very much for joining us. so does he really believe that hillary clinton is not qualified to be president of the united states? >> look, wolf. there are very big policy differences between senator sanders and secretary clinton. he articulated some right there. there are certainly many, many more. the clinton campaign, we've obviously have trouble now. they have lost seven of the last eight contests. coming into new york, think it's a rough and tumble environment there. so they begin to launch these attacks against bernie sanders' qualifications. let me say that. bernie sanders has run an issue oriented campaign, but will not be a punching bag but will not be a target for attacks, that's for sure. >> does he believe he's qualified to be president of the united states? >> well, certainly, the issues he raises suggest that maybe he is more qualified to be

president of the united states. let's put it that way. >> because he's -- he opposed going to war in iraq and she supported that legislation, is that the reason you're suggesting? >> he opposed the war in iraq. he opposed all the disastrous trade deals which have gutted manufacturing in america. he doesn't go to wall street and raise millions and millions and millions of dollars for his campaign or the pharmaceutical industry or the gun lobe or the private prison industry or any other industries. bernie sanders is funding his campaign with millions of contributions from small donors across the country. those are some of the reasons why he's a much better qualified to be president of the united states. he'll be independent and speaking for people, not special interests. >> you heard what brian fallon said, that she never insisted that he was not qualified to be president of the united states. that he in effect, bernie sanders, is lying when he says she started it. >> well, that's -- you know, listen, i was on the set of of cnn election night with you the other night. and jeff zeleny reported that the clinton campaign had a new

strategy called disqualify him, defeat him, and unite the party later. the "washington post" reported on the secretary's strategy, which was calling into question bernie sanders' qualifications. so listen, if it's a question of voracity between jeff zeleny and the clinton campaign, i'll pick jeff zeleny. >> hillary clinton took a swipe at bernie sanders' interview earlier this week in the "new york daily news." a lot of people talking about that. when he was asked how he would break up the big banks, a cornerstone of his campaign. listen to what she said. >> i think it is important to tell people what you're going to do for them. and how you can get it done. how you can produce results that will make a positive difference in people's lives. don't make promises you can't keep. know what you want to achieve. and then bring everybody together to get the results. and that's what i'm going to do. in new york, across the country, and if i'm so fortunate, as president. >> all right. so she's positioned herself as a candidate who can actually get stuff done.

suggesting bernie sanders may have great ideas, but he doesn't know how to do it. your response. >> well, look, wolf. bernie sanders does have a bold vision for america. just like other great democratic presidents of the past like fdr who accomplished only some of what he set out to do. a whole host of other benefits we still enjoy to this day. bernie sanders does have a bold agenda. that's absolutely true. bernie sanders gives 1/8th of what he proposes to get done. more than clinton has proposed in her entirety. the secretary's vision is an incrementalist small ball -- we're in baseball season -- small ball approach to politics. it's not going to get it done any more. the problems of the country are too great. we need bold sleerdship that will fight for what we need. >> the daughter of the principal killed in the sandy hook shooting called on senator sanders to apologize. she's referring to his comment the sandy hook survivors shouldn't be allowed to sue gun manufacturers. she tweeted this -- i'll put it up on the screen, shame on you,

bernie sanders, try living one our of hour lives. love, the sandy hook principal's daughter. i want you to respond to this. guns obviously a big issue coming up in new york state. >> yeah, look. absolute tragedy. i have kids. i just can't imagine what people go through who have to endure this kind of pain. i'm sure it lasts their entire, entire life. i think if you read that transcript of that interview with the "new york daily news," you will see that bernie sanders, in fact, said that in a quite lengthy segment of the transcript that he does support making changes to that law to make sure that bad actors are held responsible for their bad behavior. so i think that, in fact, they're really on the same page on this issue. bernie sanders wants to make sure that big manufacturers and big dealers who are inappropriately selling weapons in this country should be held responsible for the behavior. whether we know or should know. >> she keeps going after him for voting in favor of legislation that the nra, the national rifle association, regarded as one of

the most important pieces of legislation from their perspective. >> when you say she, you mean the secretary. >> yeah. she's accusing him of voting for that legislation, and saying that the nra was really happy with his vote. your response. >> well, look, the secretary has been all over the planet on guns. when she was in new york state originally, she wanted to license all handgun owners. then when she ran against president obama, attacked him quite vocally for being too tough on gun safety. sent out nasty mailers against him, to the point where he called her annie oakley. now suddenly on the side of gun safety again. as i mentioned before, she's taken money from gun lobbyists. i don't think she has an amount of credibility on this issue. it's expediency, really. >> when you say gun lobbyists, do you have names, specifics? because that's something that -- she's walking back from. >> well, i'll tell you, the "huffington post" reported the names of the lobbyists right there. gun lobbyists who maxed out her

campaign. in fact, held a fund-raiser for her in d.c. with a bunch of other lobbyists just last month. that's just the facts as reported. they don't like those facts but those are the facts. that's no different, wolf, really -- she says she's going to clamp down on the gun lobby, and takes their money. wall street, and takes their money. green peace documented her campaign in an affiliated super pacs received $4.5 million from lobbyists and others related to the fossil fuel industry. it's the same old game, wolf. you can't fix a corrupt campaign finance system by taking its money. >> jeff weaver, thanks very much for joining us. >> thanks very much. >> jeff weaver, campaign manager for senator bernie sanders. one week from tonight, i'll be moderating the next cnn democratic presidential debate in brooklyn. you'll see hillary clinton and bernie sanders. they will face off. remember, next thursday night, april 14th, 9:00 p.m. eastern. only five days before the new york primary. coming up, ted cruz's

comments about new york values, coming back to haunt him here in new york state. the cool reception he's getting in the state and how donald trump is using that to his advantage. what's with him? he's happy. your family's finally eating vegetables thanks to our birds eye voila skillet meals. and they only take 15 minutes to make. ahh! birds eye voila so veggie good hi...i'm pamela yellen. you may have read my bestselling book "the bank on yourself revolution". over the last 25 years, i've researched more than 450 financial products. i found that one of the best-kept secrets to help you plan for your retirement is the home equity conversion mortgage. it's a line of credit for homeowners age 62 or older. and it's offered by a company you can trust- one reverse mortgage, a quicken loans company! call one reverse mortgage now to get the details. their licensed experts will tell you if you're eligible, show you the line of credit amount you qualify for, and will

send you a free information kit. the home equity conversion mortgage line of credit is even better than a traditional line of credit... because you can make payments if you'd like, but no monthly mortgage payments are required; this program is government insured; and the money available to you increases every year. for example, if your 100,000 dollar line of credit remains untouched, it could increase to 300,000 or more, years later. so the sooner you start your line of credit, the more money you could have access to in the future. i've educated thousands of financial planners -- many are including the home equity conversion line of credit in their client's retirement plans. while this product is good if you need financial help now, it's even better if you want to strengthen your retirement plan for later. it offers a wide range of flexibility for every homeowner age 62 or older.

i believe this is a smart financial tool and i recommend that every homeowner who qualifies consider getting one now. call one reverse mortgage right now to get the details, find out if you qualify and get your free information kit. this just got interesting. why pause to take a pill? or stop to find a bathroom? cialis for daily use is approved to treat both erectile dysfunction and the urinary symptoms of bph, like needing to go frequently, day or night. tell your doctor about all your medical conditions and medicines, and ask if your heart is healthy enough for sex do not take cialis if you take nitrates for chest pain, or adempas for pulmonary hypertension, as it may cause an unsafe drop in blood pressure. do not drink alcohol in excess. side effects may include headache, upset stomach, delayed backache or muscle ache. to avoid long-term injury, get medical help right away for an erection lasting more than four hours.

john kasich campaigning here in the battleground state of new york right now. kasich visited a deli in the onx last hour, set to hold a town hall in brooklyn later tonight. certainly trying to narrow his path to the no, ma'amdation as the republican convention in cleveland in july. the significance of new york also explains why the trump and cruz campaigns, they're focusing

their attention right now on new york. trump kicked off his return to his home state with a rally before about 10,000 supporters. that was his first campaign appearance since losing to senator ted cruz in wisconsin. cruz also campaigned in new york, spending time in the bronx. the new york primary is less than two weeks away. joining us now is the arizona state treasurer, jeff dewitt, trump campaign surrogate. also ron nehring for ted cruz campaign. thank you for joining us. ron, trump wasted little time bringing up the senator's earlier remarks about so-called new york values. listen to what trump said. >> i've got this guy standing over there, looking at me, talking about new york values with scorn on his face, with hatred -- hatred of new york. so folks, i think you can forget about him.

>> does senator cruz regret making those comments? >> well, you know, donald trump gets really defensive whenever senator cruz challenges new york liberalism and new york liberals. because donald trump has been funding and bank rolling so many new york liberal democratic politicians and the new york democratic party for so long. look, wolf, everybody knows that senator cruz, what he was referring to with that and that he's challenging the liberal status quo in new york city and new york state that has produced some of the highest taxes in the country. so many people who are forced to leave new york state because of those high taxes and the economic opportunities that are cut off, as a result of it. i'm born and raised in new york. i went to school in new york. that's where i was born. that's where my parents emigrated to from germany. everybody in new york knows what senator cruz was referring to. and that's that liberal politics and near socialist politics of new york city. that has had such a negative impact under the current mayor in terms of reversing a lot of the quality of life improvements we saw, you know, under previous mayors. >> let me let jeff respond. i want you to listen, jeff.

here's how senator cruz himself explained his comment about, quote, new york values. listen. >> let's be clear. the people of new york know exactly what those values are. they're the values of liberal democratic politicians, like andrew cuomo, like anthony weiner, like eliot spitzer. like charlie rangel. all of whom donald trump has supported, given tens of thousands of dollars throughout the years. >> all right. jeff, i'll let you respond. >> well, obviously, senator cruz was pandering with the earlier comments, trying to spin it now. but earlier, he classified all new yorkers. and basically said that there's no way donald trump can be a good guy, because he's from new york. and so he insulted the entire state of new york. and he didn't seem to care back when he was pandering just trying to get votes in other places. now that he's here, that's coming home to roost. and he's cruising for a brucin in the new york primary. they're going to take it to him. as they should. he insulted the entire state.

>> let me let ron respond to that. go ahead, ron. >> well, like i said earlier, donald trump is very protective of the liberal democrat politicians. he's been bank rolling for years. made sizeable investments, huge contributions to the democratic party, for example. and as well as new york city politicians and the liberal democratic governor of the state. so, of course, he's going to be defensive and of course he's going to use that. because he wants to do anything he can to take the subject away from the fact that he just got trounced in the state of wisconsin. he said he was going to win there. and i think it's important to see what happened in wisconsin, because exactly what we said would happen has happened. in that as the number of republican candidates has been reduced from 17 down to a two-person race, our numbers have gone up and we're seeing that consolidation of the republican, the conservative base behind senator cruz. of course, donald trump doesn't want to talk about that. but that's the reality. that's what he's really facing as his race goes forward. >> jeff, trump has to do well. new york is his home state, just like cruz -- won his home state

against texas. it's a given. don't you believe that trump should win his home state, win it decisively? >> he will win decisively. and i think it's kind of hilarious when you hear the cruz campaign call it a two-man race when cruz is going to come in a distant third in new york and other states east. obviously, it's not a two-man race, even though it should be. senator cruz is going to come in third. >> there was a monmouth university poll, as you know, ron, that did have senator cruz in third in new york. you saw that poll that came out yesterday. what do your numbers show? what does your internal polling show? is he going to spend a lot of time in new york or move on and devote energies elsewhere? >> well, senator cruz will be in new york campaigning just like he is today. many, many times between now and the new york primary. what's really interesting to see is that donald trump very suddenly cancelled his appearances, both in california, where he was supposed to be tomorrow, as well as in colorado over the weekend in order to devote more time to campaigning in new york. that doesn't look like a candidate who is particularly

confident in his performance in his own state to me. but -- why would he -- you know, he made commitments. like he's cancelled on previous commitments in the past like c-pac. colorado, he cancelled that. we had information and it was already public, that he was going to hold a news conference at his location in california tomorrow. that was suddenly cancelled. we have an indication he was trying to organize a rally in the city of fresno, california, for friday. that was suddenly cancelled. so, you know, these are the moves of a candidate who is confident and has his campaign together. we have seen the reports about the troubles that his campaign is having. and this would seem to be indicative of that. >> let's let jeff respond. is he nervous about caring his home state? >> you saw the poll. we have other polls -- >> why did he cancel visits out west? >> there's a lot going on right now. don't forget his daughter had a grand baby. there's a lot happening here. it's nice to be home. a lot of the staff has been home just a handful of times in the last four months. so we have a lot of great things

happening here. but nothing like that. in fact, i don't think he even half of what he said was true there. trying to spin it into saying the campaign is in trouble, and -- >> no, he cancelled -- >> four times as many votes as ted cruz does here. >> he cancelled his event in los angeles. he was supposed to have a press conference. he was going to california. he was trying to organize rally in central valley and cancelled and suddenly spending time in new york. he's rediverting his resources in new york. they scheduled it, publicized them and cancelled them. that's absolutely true. and i'm just curious as to why. >> go ahead. >> all we're doing -- look, these events were barely scheduled, a few of them. and they were tentative. >> they were announced. they were not tentative. >> do you think honestly we're worried about new york? >> his -- i'm just curious as to why you would -- why would you schedule a press conference in los angeles, at his property in rancho pal he is verdicts, told the press you were going to be there, told people you were

coming and at the last minute that gets cancelled. i'm just curious as to why that was done. >> why does senator cruz run bills to triple the amounts of immigrani am to come into the country. >> i answered the question. >> that doesn't answer why these events from were suddenly cancelled. why would you schedule them, why would you tell everyone that you're coming to california, and then suddenly reverse it? why would you tell people in colorado you're going to be at their convention and then suddenly cancel it? i'm curious as to why. what's going on as to why these events -- was this a staffing error? and why? >> we're out of time. but very quickly, go ahead. >> the better question to ask, senator cruz is telling kasich to drop out because he has no mathematical chance to win when senator cruz has no more mathematical chance to win after the 26th. >> not answering the question. >> ron nehring, we're going to move on. but you guys were excellent in your respective presentations. thank you very much. we'll have much more on this coming up.

by the way, an important programming note to our viewers. our dana bash will interview senator cruz later tonight, 7:00 p.m. eastern right here on cnn. thanks to both jeff dewitt and ron nehring. one of donald trump's most prominent supporters, ben carson, on cnn at this hour earlier today. dr. carson was asked to clarify comments he made recently that there were, quote, probably better republican candidates than donald trump out there. listen to this. >> you think there are better people out there to be president than donald trump? >> i don't think you have to really think about that. it doesn't matter what you're doing. there are better people than me. at neurosurgery. there are better people than you being a broadcaster. you know, there are better people at everything. >> when you say that there are better people out there, did you have someone in mind?

>> i don't think that that's a useful place to go. >> all right. coming up, we're going to sort through the mad scramble now for delegates from so-called super delegates. what does it mean for both parties' conventions in july? our team getting ready to break it down, for you. hey! this is lloyd. to prove to you that the better choice for him is aleve. he's agreed to give it up. ok, but i have 30 acres to cover by sundown. we'll be with him all day as he goes back to taking tylenol. yeah, i was ok, but after lunch my knee started hurting again so... more pills. yep... another pill stop. can i get my aleve back yet? for my pain... i want my aleve. get all day minor arthritis pain relief with an easy open cap.

where do they stand now? >> we're actually on the verge of talking about two potential contested conventions, completely wild. one is far more likely than the other. let's look at the democrats first. the magic number here is 2,383. the number of delegates hillary clinton or bernie sanders needs to win. as it credible stands, with more 1600 delegates on the map remaining, clinton needs to win 36% of those. bernie sanders, 77%. so a clear lead. now take away the super delegates. this always the wild card here. free agents that can go any way they want. hillary clinton 129 delegate lead. that's what the sanders campaign wants to look at and say they can flip them over. reality is, in democratic rules, super delegates matter. hillary clinton with a major lead in super delegates. if you look at republicans, and we know the math. 1,237, the only number anybody cares about. contested convention looking far more likely. donald trump right now post wisconsin, 59% of the delegates remaining on the board. that's what he needs to get. ted cruz, 8 %.

john kasich eliminated. you want to talk about why cleveland right now is looking like an open convention. those numbers right there. >> yeah, because trump, he inconsistency he can get that 59%. >> a pathway there. very narrow. >> easier to get 59% than 88. so ron, give perspective, history perspective. where the other candidates have been in the delegate race in past elections. >> yeah, i think it's extraordinary. we are i think witnessing the emergence of a new normal. if you go from the ronald reagan-gerald ford race in 1976 until hillary clinton and barack obama in 2008, really only one race that was fought all the way up to the final day with the outcome, and gary hart and walter mondale in 1984. that was truly in doubt all the way to the end. but what we have seen in the last, what, eight years now between hillary clinton and barack obama in '80 and now the democratic and republican race this year, with more money, more media attention and more polarized parties, there are opportunities for candidates to extend these fights beyond the ending point that we had seen in

previous races. i mean, it really would be extraordinary if we get to the final day on both sides and still have the nominations, at least technically or somewhat in doubt. it really i think is a change that we're witnessing and probably going to be with us for a while. >> it would certainly make those conventions obviously a lot more exciting. we've heard of pledge delegates, we have heard of super delegates. phil, there's also unbound delegates. explain. >> and to ron's point. why all of a sudden these matter. unbound delegates. cnn has found there are 183 unbound delegates coming from six states and three territories. here's a good way to look at them. super delegates on the republican side. not required to vote for any candidate and that is why you see with only 20 -- of these 183 committed, each campaign is targeting these delegates. why? you talk about that 1,237 number. say donald trump comes up 50 delegates short. he can look at these unbounds and go after them. i was in fargo last week. they were choosing 28 unbound

delegates. ted cruz showed up. ben carson showed up. every campaign focused on that. the next state to pay really close attention to, pennsylvania. 54 unbound delegates. pennsylvania is about to get a lot of love from all three campaigns. >> a week after new york. the 26th. guys, thanks very much. up next, stuck on the front lines. families recall the horror of becoming human shields for isis as their villages become battle zones. our own arwa damon risking her life right now to report live from iraq. she'll join us. and a brand-new video of a suspect in the brussels airport attack. what it reveals about how he got away and why police are now desperately needing the public's help.

the european law enforcement agency and the fbi, they have joined forces in it an effort to strengthen the fight against terrorists, fighters. it comes as belgian authorities receive sharp criticism. today they issued a fresh appeal for information leading to the identification of the so-called man in the hat. he's the suspect in the brussels airport suicide bombing that killed 16 people last month.

prosecutors have pieced together closed circuit television footage. you're seeing some of it. of the suspect after he left the airport on foot. they also released a map of the path they say the man took, indicated by a tiny red dot. authorities are desperately looking for anybody who may have spotted him during that time. i'm joined by paul cruickshank who spent time looking at this video. what stands out for you? >> when the bombs go off, he walks very briskly out of the departure terminal and continues walking for quite a long time. and indeed, walks all the way back into the center of brussels, and back towards the commune of scarbeck in brussels where he set off, they understand, earlier that day from the bomb factory, picked up by a taxi driver who dropped three of the bombers off at the airport. one didn't die in the attack. he's at large. and they clearly released this

cctv surveillance now, because they just do not know who he is and they want to identify him before he is potentially able to strike again. >> cctv, the closed circuit tv. at one point, he threw away his raincoat. and forensic experts, others, they really want to find that raincoat. what evidence potentially could it show? >> it could be a gold mine of clues. so you're looking at pocket, things like receipts or a taxi receipt or something like that, which could hone you in on the guy's identity, the guy's location, where he has been in the last few days. if he's not careful and he's left something -- even a small receipt or something like that, in the coat. they can also do dna analysis and match that to dna of known terror suspects to see if he's somebody on the known database. >> paul cruickshank, thank you very much. hopefully that video will help someone identify the terror suspect. syria, the state run news agency is saying isis terrorists

captured workers at a cement company. it makes it harder to defeat isis. mosul, the second largest city in iraq. cities with more than 2 million people. there are grave concerns about civilians being caught in the cross fire and about isis using them as so-called human shields. our senior international correspondent, arwa damon, talked to people who experienced firsthand the life of people under isis rule. she has more in this exclusive report. >> reporter: the latest arrivals are not those who fled isis. there are those who say isis used them as human shields and didn't let them leave. they're from a handful of villages. the men are kept at the camp's mosque. aprecaution.

they are concerned isis is in the village. like many here, he does not want his identity revealed. he still has loved ones at the mercy of isis. and has already witnessed, lost too much. abu and his family could hear the army's advance. hoped finally that they would be saved. but in the fierce clashes, abu's younger brother was hit as he pulled his niece away from the window. he shouted, i am shot, get me, abu sarat says. the memory of that movement so painful, he can no longer control his emotions. he said "i don't want to die." but he bled out. with us, abu is able to leave the mosque grounds, and we head to see the rest of his family. he says they did not flee when isis first arrived nearly two

years ago. because his elderly mother could not run away. a mother who has buried her son. what is left, she now questions. at least god spared the rest. their stories of life under isis make your skin crawl. abu worked at a hospital in mosul. i was forced to keep working. he said, if you don't, i will leave your head on the hospital gate, he tells us. once, he was stopped in the street and forced to witness a public mass execution. in another instance, on the way to the market, he says, we saw people hanging from the electricity pole. we asked why. they said they were trying to leave. if you try to escape, this will be your fate. the women also hide their faces. but little can hide the lingering fierce. the overwhelming psychological trauma or the pain. this woman says the house isis held her family in as the iraqi

army advanced was hit by a mortar. she was injured. her 15-year-old son killed. her last image of him, with blood coming out of his eyes, nose, mouth. it's all memories, she says, before it becomes too much, and she walks away. >> heartbreaking, indeed. arwa's joining us live from erbil in iraq. very disturbing accounts in this report. what else were you told by those you've been talking to? because this is clearly a critical moment right now. >> it is, wolf, and the vast majority of them are still unspeakably concerned of those they know who still live in the numerous villages that isis controls, as well as those who still live in mosul, iraq's second largest city. they say that they do hope that the iraqi army will be able to advance towards them. that is an advance that at this stage has been paused, whilst they wait for reinforcements,

but they're also afraid that isis going to continue to employ the same tactics and not allow people to leave. their stories of suffering are incredible. fathers worried about their daughters. worried that isis fighters would come and ask for their hand in marriage. then they would not be able to say no. they would be forced to give their daughters over to isis. those who are worried about the wrong step, the wrong word. that would end up seeing them lashed or, even, woulrse, executed. isis going out and kidnapping people who they suspected were part of the iraqi security forces and how they managed to effectively manipulate the population in these villages and in the city of mosul by convincing them to stay behind, convincing them that they would not be impacting their lives and then seeing the truth emerge and having to suffer under this brutal isis regime for so long.

it's an impossible situation that they find themselves in, wolf. >> you spent a lot of time, also, arwa, with the iraqi army. what's taking them so long? it's been two years now since isis took over mosul, the second largest city in iraq. why can't the iraqi army, which has hundreds of thousands of troops, simply move into that city and recapture it, liberate it? >> wolf, they're still fraught with problems and challenges at every single level. so far, when they initially launch this operation, the first phase of it, they managed to fairly quickly recapture three villages. they were very brewant about that success. then they tried to move on to another village recently and there they actually managed to get in, backed by coalition air strikes, secure most of the village, wolf, and then there was some sort of misstep, miscommunication, that led to their inadvertent retreat, and then isis moved back in, and now

these operations are unhold until reinforcements can arrive, and this is just an indication of just how difficult it is going to be for the iraqi army to press forward, even with the u.s. advisers, even with the u.s. and coalition air support that they are currently receiving. add to all of that, the population in mosul is still there. isis has been able to fortify itself in that city for the last two years. we've been seeing isis employ g ing tactics such as car bombs, booby trapping pass angs and homes. so pushing into mosul is not something that is going to be happening any time soon. it is going to be a very difficult battle, arguably, a big challenge for iraqi and for the u.s. >> arwa damon, reporting for us, thank you very much for doing what you're doing. you're doing a great job for all of viewers. that's it for me. thanks very much for watching.
