tomorrow. in the meantime, "ac 360" with anderson cooper begins right now. good evening. we begin with breaking news. new details about the man police say is responsible for these terrifying and potentially deadly moments today on capitol hill. some fleeing. others told to shelter in place. larry russell dawson, 66 years old. here he is being taken away on a stretcher. he was already on the radar before today. already known to them before. they say he pulled a gun at a capitol checkpoint and police opened fire seriously wounding him and leaving a bystander with minor injuries. brian todd has been covering the story from the early moments. what do we know about what's going on right now with the suspect's truck? >> yes, anderson. we can tell you this is confirmed to be his vehicle, this silver dodge ram pickup truck. it looks like police are about to tow it but they've been here

for a couple of hours surrounding the vehicle. we presume they've checked it before this. but they do appear to be ready to tow it. they are taking some kind of measure mtd to the vehicle and doing some other checks on it. this is confirmed to be the suspect's vehicle. interesting he parked it here on the west side of the white house by the reflecting pool next to the botanical gardens. he had to walk quite a long way up capitol hill and around the building to get to the place where this shooting took place, where the visitor center check-in is where the metal detectors are where this incident happened. as far as what happened in the incident, according to police, this suspect walked through the metal detector. set off an alarm and then pulled a weapon. he drew the weapon and according to law enforcement sources waved it around. at that point law enforcement officers fired on him and wounded him. he was taken away and is recovering from his wounds. there was also a female bystander who was wounded by

shrapnel, we are told. we got word a short time ago she was to be released from george washington university medical center. >> what do we know about this guy? what do authorities know about this guy? he was known to them. >> he was, anderson. the police chief of capitol hill said he was known to police before this. but what we have learned from law enforcement sources, first, they have told us his name is larry russell dawson. his name has not been publicly identified by police, but two law enforcement sources tell cnn his name is larry russell dawson, and we've got court documents here, that i'm holding and have been looking at them. according to these court documents he disrupted a session of the house of representatives back in october of last year. according to these court documents, he came in and yelled he was a prophet of god, and he was forcibly removed from the house chamber. now he's a 66-year-old man from

tennessee and, indeed, the vehicle you are looking at has tennessee plates on the back. but he is identified by law enforcement sources as 66-year-old larry russell dawson. the police chief of capitol hill said he was known to them, and we have details of that incident that he disrupted the house of representatives in october. forceibly removed and then ordered to not come anywhere near the chamber. he wrote them a letter back in january saying he was not going to comply with that order. >> the white house was also locked down today. that was a separate incident, correct? >> it certainly was, but it was very strange because it happened at almost exactly the same time. at about 2:45 p.m. eastern time as the capitol hill shooting. according to law enforcement, a woman who was at the easter egg roll, inside the grounds and had a ticket. she tried to remove a temporary barrier. and that is grounds for your removal and arrest. she was arrested. this is the same woman who back

in march of last year, i believe it was, tried to jump a white use barrier. so she has been known to white house security people as well. but again, these incidents were not related but it was strange they happened about the same time. >> strange she was able to get a ticket this time. brian todd, thanks very much. democrats, republicans alike campaigning hard for the next big prize. wisconsin next tuesday. the remaining three republicans also preparing to face the voters and their questions in tomorrow night's cnn town hall in milwaukee which gets under way at 8:00 tomorrow. donald trump, ted cruz continuing the war over their wives with trump also threatening a legal battle over delegates. more on all of it from our sara murray. >> reporter: donald trump is getting outmaneuvered by ted cruz in the delegate fight. >> i won louisiana, and now i hear he's trying to steal delegates. welcome to the republican party. >> reporter: and now he's threatening to sue tweeting, just to show how unfair

republican primary politics can be, i won the ste of louisiana, and get less delegates than cruz. lawsuit coming. trump's latest threat comes after a "wall street journal" report revealing even though trump narrowly won the state of louisiana, cruz appears poised to pick up more delegates. >> i'm always amused when donald doesn't know what to do, instead threatens lawsuits. >> reporter: trump refuses to back off his attacks on cruz's wife, heidi. >> i didn't even know it was necessarily a very bad picture of her versus melania. >> reporter: trump speaking with conservative talk radio host charlie sykes. >> before you called into my show did you know i'm a #nevertrump guy? >> that i didn't know. >> reporter: sykes repeatedly asking if he'd apologize to heidi cruz. >> most real men when they screw up say, i was a hot head. i apologize. >> i believe in apologizing. before i'd think about apologize, he owes me an apology

because what he did was wrong. he sent out a picture to people in utah -- >> he didn't and you know that he didn't. you know it was a superpac. >> reporter: cruz also making the point that a facebook ad featuring an old modeling picture of melania trump came from an anti-trump superpac and not his campaign. >> the ad they put out was deplorable. as soon as i saw it i denounced it. >> reporter: the republican rivals are trading jabs over a tabloid report about the texas senator. cruz accusing trump and his backers of planting the story but offering no proof to back up his assertion. >> these are complete made up lies. they are garbage. but you know, it's indicative of just how low donald trump will go. >> reporter: a claim trump denies. >> i had nothing to do with it. the campaign had absolutely nothing to do with it. >> reporter: as the campaign devolves into an unsavory personal battle, john kasich is calling for civility. blasting out a fund-raising e-mail declaring families should be off limits. enough is enough with the mud

slinging and the personal attacks. >> sara murray joins us from the sites of a kasich rally in madison. any indication how the fight is afecting voters there? >> that's right, anderson. both of them will be campaigning here this week. ted cruz already is. right now if you look at it, it looks like ted cruz has the upper hand. we haven't seen conservative voices on the radio sort of consolidate around donald trump in wisconsin like in other states. we haven't seen party officials or other republican leaders here throw their support behind donald trump. right now is looks like ted cruz has an edge going into this. and then john kasich. his campaign made it clear today they are realoeicating some of their resources. they are nodding to the fact they know they aren't in the hunt for victory here in wisconsin but are still in the hunt for delegates. it will be interesting how this all plays out when it comes primary night. >> sara murray, thanks. want to bring in trump

supporter kayleigh mcenany and kevin madden, tara setmayer and ana navarro. ana is a republican strategist. kevin, are you surprised this personal battle between cruz and trump is continuing, that neither seem willing to let it go? at what point if at all, does it have an adverse impact on them? >> very much so. look, it's in the interest of both of these campaigns to have that issue no longer be a distraction. to what should be a core message, particularly when you look at having an international event only four, five days oopg that will, in many ways, will refrain the stakes of the race between a republican candidate and a democratic candidate. and so for these candidates to really miss the opportunity to move to talk to voters about the anxiety and fears they have about international terrorism, what we need to do to increase america's national security posture around the globe in the face of that threat, that is a

big mistake. they are actually ceding that opportunity for hillary clinton to seize that's commander in chief mantel that she so desperately wants in a general election. it's a huge distraction for us that two grown men are still fighting over twitter fights from three days ago. >> kayleigh, you are a trump supporter. are you concerned this nastiness could be disrupting whatever momentum trump might have had into wisconsin, instead of acting like a front-runner, staying above the fray, he's getting in these twitter wars about wives and dirty tricks. >> yes, i'm very concerned. i want both trump and cruz to come out. maybe they need to meet in some back room like cruz did with ben carson and come out with a detente of sorts. they both need to stand up and say enough is enough. trump should apologize for retweeting that picture of heidi cruz. cruz should apologize for calling trump sleazy and surrounding himself with henchmen. covin is exactly right. instead of talking about obama

doing the tango in argentina and attending a baseball game during the brussels terror attacks, we're talking about twitter wars. this is crazy. the republicans are going to lose in november and hillary clinton will walk straight into the white house unless both of these men stand up and say, enough is enough. let's talk about terrorism because i think the american people deserve that. >> tara, you hear what kayleigh says. does cruz bear some of the responsibility that he's done some mud slinging as well? >> well, i think ted cruz probably at this point needs to move forward. i agree with that. but i don't think that it's fair to draw a moral equivalence between ted cruz defending his wife and donald trump deciding to tweet out things that aren't true and continuing to perpetuate a lie about the ted cruz campaign. the ted cruz campaign had nothing to do with this ad. it's illegal for superpacs to coordinate with one another yet donald trump knows this but he continues to lie over and over again, blaming ted cruz saying that he knew, they coordinated.

so this is casting aspersions on ted cruz. he feels compelled to not only defend his wife but also to defend the integrity of his campaign. they are right. kevin and kayleigh are right. this is a blown opportunity. we really should be talking about terrorism and what happened and what the next commander in chief would do differently than the failed leadership we have now with barack obama. in a discussion like that, ted cruz would dominate the conversation because he knows what he's talking about. unfortunately, for donald trump, he's willfully ignorant on issues of critical importance for the presidency. this is why he continues these kind of distractions. he'd rather have his tabloid back and forth, these juvenile games because that's his areina. he distracts from the fact he doesn't know what he's talking about. >> kayleigh, do you believe that's true? that's the cruz accusation. donald trump is doing this to change the topic because he doesn't feel confident talking about foreign policy issues.

obviously, as a supporter, i'm sure you disagree. >> yeah, i completely disagree. that's a farce. when you look at history, history is a good indicator that donald trump knows about these issues. he was on the right side of the iraq war. he was against the iraq war before hillary clinton, before almost any republican was. "the new york times" wrote an article about him a few weeks ago calling him crazy for pointing to brussels and saying, hey, look what's happening in brussels. radical islam is taking over the city. he said that and "the new york times" made fun of him. and he's been predicting some of these attacks and seeing what's coming down the pipes. to say he doesn't know about foreign policy is just ridiculous. >> ana? >> he was for the iraq war before he was against it. that's on record. and he -- >> and he was against it before anyone else was, tara. >> that's ridiculous to suggest that he is some kind of foreign policy savant. he wasn't paying close attention to any of these. >> let me bring in ana. lindsey graham said the best way

to stop donald trump is for cruz and kasich to team up. some unity ticket. how likely -- is that at all even possible? as long as they keep splitting the non-trump vote, he'll be going into the convention but you have kasich saying he's not interested in being anybody's vice president. certainly cruz isn't as well, so he says. >> look, i think the idea of a unity ticket is somewhat idealistic. you'd be faced with a proverbial question, who goes on top? but i do think that certainly the gurus, the political gurus from ted cruz and john kasich could get together and figure out the math of the primary and say you might do better in wisconsin than i will. you take wisconsin. you might do better in pennsylvania, hey, john, you take pennsylvania. i think they can take a look at that map and be strategic. and let me tell you something about the discussion that was -- that preceded your question. once we're done arguing about donald trump's esp when it comes to foreign policy, i just want to say, i don't care who started this fight.

i don't care if it was ted cruz, if it was some unassociated superpac or donald trump. what it is is time for it to stop. it's disrespectful to the office. it is disrespectful to republican voters who have to go out and make a choice between these two or three guys to give us this choice. we have now had a primary where we've discussed references to body -- the sizes of body parts, where we have had name calling. now we've got a whose wife is hotter? my wife is hotter than your wife contest going on while there are terrorist attacks going on all over this globe. they are not running for fourth grade class president. they are running for commander in chief of the united states of america, and it is time that republican voters and voters around this country demand that they start acting like adults and with the dignity this office deserves. >> kevin, how important is wisconsin for ted cruz on tuesday night? we've got this town hall tomorrow night there. governor scott walker said this

goes to a contested convention, he thinks it will not only be someone not currently running for president. in terms of for cruz, though, how important is wisconsin to prove that he's got momentum? >> yeah, look. it's very important in the sense that's not only is it -- will it help ted cruz gain some momentum, but he has to start putting a dent in this idea that donald trump is going to get to that 1,237 threshold of delegates that he'll need in order to go into cleveland already with the nomination in hand. so every time that he can stop donald trump in little ways and big ways, through all these next contests is very important. the other important part is the rest of the calendar gets very favorable for donald trump. for those voters looking at this race in new york or connecticut or delaware, maryland, later on in the calendar, if cruz can start to make an argument he can beat donald trump one on one, then he can possibly begin to gain some momentum in those states that right now are very

strong for donald trump. >> we'll continue the conversation throughout the next two hours. coming up next, the delegate numbers that could make donald trump the nominee or deny anyone a clean shot at the prize. latest, the arrest that led authorities to believe they'd caught the suspected third brussels airport terrorist. what happens now that they have to release that guy because akair apparently he's not that guy. we'll update you on the entire investigation and the manhunt that goes on when we continue. ♪ ♪ ♪ lease a 2016 lincoln mkx for $399 a month

with all the back and forth between trump and cruz over their respective spouses, it's easy to lose sight of the people they're battling over. delegates. hundreds of demgatts still at stake on the road to the nomination. for bernie sanders and hillary clinton, it's the same thing. it's all about finding the stage where they can find the number they need. tom foreman joins us. >> these are all the states donald trump has won so far out here. here are the states ted cruz has won. and we know marco rubio won a state and puerto rico and we know that john kasich won his home state of ohio. so if you put it into math in terms of the delegates you're talking about, this is what it looks like. trump has a substantial lead. more than halfway toward that magic number of 1,237, the number of delegates you need to

clinch the nomination before the convention. cruz a good bit back. kasich way back over here. is it possible for john kasich to win enough people at this point to go past both these candidates and get to that number? can he get that many delegates? no. the problem is if john kasich won all the delegates that remain, he'd still come in short of the magic number. his real hope is to hang around to be involved to do well until you get to a contested convention if you get there and make a deal on the floor. what about ted cruz? can he do better? better than kasich in terms of the numbers right now but he has a very tough haul ahead of him. he has to win more than 80%, much more than 80%, of all the remaining delegates if he wants to clinch the deal before this. so on the republican side, simple equation. for all the noise about this campaign, the numbers still vastly favor donald trump. >> take a look at the democratic side. bernie sanders had a very good weekend. can he catch up with hillary

clinton? >> again, it's a tough haul right now. look at hillary clinton's numbers. she's done very well with all these states she's won and here are the states bernie sanders has won over here in a slightly difference color of blue. if you put them side by side and look at their delegates, then look, clinton has a lead over sanders here. she's closer to getting to the magic number of 2,383 delegates, but here's another way of looking at it. she needs 63% of all the remaining delegates to clinch that before their convention. and he needs 77% of all the remaining delegates. that's a substantial difference although still a challenge for both of the candidates. much bigger challenge for him. he has to perform very well in wisconsin, the next big race coming up. a state that is almost 90%

white. he tends to do better in places with fewer minorities. she does better with minority voters. he not only has to do well there but in powerhouse states like new york, her home state, new jersey, pennsylvania, tons of delegates out there in places like california. she will fight him tooth and nail in all of those places. he has to come out overall with about three or four of all the bemaining delegates in his camp, on top of which, even if he does that, when you get to the convention, look at the superdelegates. these are big important leaders. they are right now strongly in hillary clinton's camp. not so much in his camp, although this is a changeable number. they can change on the convention floor if they think he is surging forward. this still remains a difficult haul for bernie sanders. >> sanders supporters say, look, a lot of -- there were a lot of superdelegates who pledged to hillary clinton in 2008. they ultimately switched and went for then candidate obama.

a former top adviser to president obam adavid axelrod knows what the delegate chase looks like. and gloria borger, our chief political analyst. getting delegates to switch sides. obviously in 2008, hillary clinton started with ea huge superdelegate lead. obama had a nearly 2 to 1 advantage. how hard is that to pull off for sanders? >> i think it's very hard for him. it's quite different in 2008 when barack obama was a minority candidate. he was getting huge numbers among minority communities which are the most faithful base of the democratic party. he was winning some significant states, even states that were all white. his appeal was very broad. his depth of support among the base of the party was very strong. would have been very hard to deny him the nomination. bernie sanders isn't in that

same position. for him to be the nominee, he'd have to start ripping off big victories in large diverse states which is something he hasn't been able to do so far. >> how likely is it this time around? >> i agree with david. i think it's not likely. i was talking to a senior sanders adviser to describes it this way. he said our first goal is to get those 200 uncommitted superdelegates to come our way. and then once we start winning, once we start winning, then the rest, you know, the rest will hopefully follow. they have to succeed in winning those states, as david was talking about. >> when you look at the -- >> you can see the theory. the theory is that if they prove themselves to be a -- it's like the kasich theory in the republican election, which is their argument is we're doing well in the general election.

we're doing well in polls and, therefore, people should turn to us. but a lot of democrats are suspicious as to whether bernie sanders will be doing as well if the republican party was turning its guns on him as they have been hillary clinton. there's not a real confidence his numbers would hold up over time. >> on the gop side, do you think at this point they'll definitely have a contested convention? that's obviously what kasich and cruz are depending on. >> well, i'm -- i think -- i've said from the beginning if donald trump gets close, they'd have a very difficult decision to make, which is are they going to deny a guy within hailing distance of the nomination and have a convention filled with malcontents and people who feel they've been betrayed? and it's like a choice between a punch in the nose and a knee to the groin. do they want to antagonize those people by choosing a candidate they think will be stronger in the general election or go with the will of what is close to a majority of their delegates.

>> it's hard to imagine if he's leading in the vote, if he has the most delegates, them denying him. >> he has to cross the finish line. and there is a question of how organized donald trump is. today he threatened to sue the state party in louisiana or the republican party because he won louisiana by a few points but is not getting as many delegates. and one reason is the cruz people are very organized. they are getting all these roubio delegates and uncommitted delegates. so you have to be able to get yourself across the finish line. i think either way, you are going to have a lot of unhappy people at that republican convention. whether trump wins or whether he doesn't win. i think it's very likely to be contested. we'll just see what kind of a margin trump goes into the convention with. >> gloria borger, david axelrod, thanks. coming up next, the two

authorities thought they had caught one of the men but apparently they were wrong. cnn's pamela brown has the latest. >> reporter: today the mystery deepens about the third bomber at the brussels airport seen in this video pushing a cart believed to be holding a bomb in a black bag. his identity and whereabouts remain unknown. a man identified by authorities as faycal c. was arrested and charged with terrorist murder. cnn has learned investigators initially thought he was involved in the attack based in part on information given to authorities from the cab driver who picked the bombers up. but the belgian prosecutor released a statement today saying faycal c. was released from custody because the clues that's led to his arrest were inconclusive. they tell bfn his client is innocent. as authorities try to identify the alleged second metro bomber, the hunt is on for this syrian man known as 28-year-old naim al

hamed. he's described as very dangerous and probably armed. and is considered a critical figure in both the brussels and paris attacks. he is one of at least eight suspects european security agencies are searching for in connection with the attacks. >> this is a vast network. it is interlaced at many points and separate at many points. that means you have to go both at the center and at the tentacles at the same time. >> reporter: belgian police continue to sweep the country for more terror suspects. they conducted 13 raids on sunday. three men are now charged with participation in the activities of a terrorist group. so far the terrorist network in europe has extended from belgium to france, germany and italy where an algerian national was recently arrested on suspicion of producing fake residency documents linked to the attacks. >> pamela brown joins us. you're learning more about faycal c. who was released. >> that's right. u.s. officials along with officials in europe were very

suspicious about this faycal c. from very early on. his name was going around a day or two after the attacks and then as we know, he was officially charged with terrorist murder on friday. and then i think it came to a surprise to several officials i've been speaking with that he was released from custody as we heard from the prosecutor. they didn't think they had enough evidence to keep him in custody. they thought he was a leading contender initially because of this information the cab driver who picked up the bombers had given authorities. he matched the description apparently. also some intelligence that was gathered during the course of the investigation. led authorities to him. although there was a list of people this third bomber could be, he was a leading contender. now officials are saying they have these list of names but they don't know who it is. they thought they had a good lead with him. clearly they didn't. his attorney faycal c.'s attorney came out today and said his client is innocent, that he doesn't even match the height

description, that he's short. the suspect in that picture is tall. there are many inconsistencies. and so it's a bit of a fruftseration for authorities in this investigation that they still don't know who that third bomber is. >> pam brown, thanks. a lot to discuss wither panel. joining me is terrorism analyst paul cruickshank. cnn national security analyst juliette kayyem who was u.s. assistant secretary for homeland security. and intelligence and security analyst bob baer. what's the latest you're learning from your sources about the investigation. >> the guy at the airport who ran away -- >> and they still aren't clear who he is? >> they don't know who he is at this point with any certainty. there are a number of contenders. one is naim al hamed that pam mentioned in the peace. someone who came through syria to greece and then on to europe. picked up by salah abdeslam at a

refugee camp and his dna was found in the bomb factory in schaerbeek used for the brussels attacks. we've been told by a source close to the investigation he's believed to be operationally involved in the brussels attacks. what's not clear is whether he was at the airport, the guy seen on cctv at the metro station or at neither of those places. but they're looking for him throughout europe right now. they are looking for eight suspects in total that they believe are connected. >> eight of them? >> to the paris and brussels attack. there was a bulletin that went out the day after the brussels attacks. we've been briefed on details of that bulletin. >> the fact he was arrested and charged with terrorism murder and then released, does it speak to the belgians' capabilities, the infiltration of some of these communities, of potential suspects? are they just rounding up the usual suspects? >> anderson, that's exactly it. they clearly were not inside this cell. they didn't have a human source.

these people were staying on the internet, off cell phones. so what they are doing now is simply reacting by picking up the usual suspects. and, you know, i call it preventive detention. knocking down doors. interrogating people. making arrests. and if they don't have the evidence or the people have an alibi, they have to release them. this guy in the picture, and i don't know why, but clearly didn't want to be identified. that looks like he was wearing a disguise. did he intend to get away or was he supposed to be a bomber? i can see there are problems, and i share their fruftseratist. they simply don't know what they are up against. >> juliette, they obtained pictures of the abdeslam brothers partying eight months before the attacks. they drank and smoked pot. does that fit into the profile of somebody who becomes a

jihadist? somebody who becomes a terrorist? >> absolutely. if we look at the profile of most of these guys, especially those involved with isis, there's often a period of partying and girls and alcohol and having a good time. and then what we saw with the paris bombers is they essentially went dark. went black for a period of time and then emerged as the terrorist. and that tells me two things. it shows how difficult it is for western european and u.s. law enforcement agencies to get these guys because they are essentially just petty criminals and some small percentage of them becomes terrorists. and it also tells me that people within the community knew this was happening to that set of terrorists. that they used to be outgoing guys and then all of a sudden, they aren't. so when we talk about community engagement in brussels and europe getting better about outreach, it's for that reason. it's because it's the community that's going to know. >> it does seem, paul, that's a

critical factor in all of this. busting down doors is one thing. but unless you have connections to the larger community, that's the front line. those are the people who are going to have the greatest amount of information and knowledge. they are the ones who are going to see something and you want them to say something. >> absolutely right. they are the front line defense. the muslim community and places like molenbeek and other parts of europe. they need to come forward and to tell authorities any suspicions they might have. they need to do a better job. >> the police haven't -- i don't know whether they've been able to make inroads or have made much of an effort. doesn't seem they have the connections. >> there are attempts to make inroads, and there are muslim members of the muslim community all across europe that have provided tips to law enforcement. that's definitely happening as well. we have to say that is happening. but that intelligence vital because these isis operatives coming back to europe increasingly using cryptic communications. there was an interrogation of a

french recruit by the french authorities this summer. and he revealed they set off an elaborate system of communications where they encrypted using a software tool on a thumb drive they were given in syria and scrambling the message and putting it into a file-sharing site that only those who had the passwards for. all this creating a communication system to allow them to operate more freely in europe. that intelligence even more vital than ever before. >> bob, the obama administration says these isis attacks are proof the west is winning in iraq and syria. do you buy that? >> unfortunately, that's true. with the taking of palmyra by the syrian government, by the attack on mosul, which has already started, the fall of ramadi, the islamic state is on the run. we all predicted this a couple of years ago. on the other hand, it is like a cornered rat. it will strike out when it can.

it will bite and it will probably bite again in europe. >> bob baer, juliette kayyem and paul cruickshank. coming up, a former athlete who played college basketball in the united states, lives through the brussels attacks, now in the hospital. he's thankful to be alive but wondered why he lived when so many others did not. you'll meet sebastian belan and hear his incredible story next. taking one claritin every day of your allergy season... ...for continuous relief. with powerful, 24 hour... ...non-drowsy claritin, live claritin clear. every day. i've had moderate to severe plaque psoriasis most of my life. but that hasn't stopped me from modeling. my doctor told me about stelara® it helps keep my skin clearer. with only 4 doses a year after 2 starter doses... ...stelara® helps me be in season. stelara® may lower your ability to fight infections and increase your risk of infections. some serious infections require hospitalization. before starting stelara® your doctor should test for tuberculosis. stelara® may increase your risk of cancer.

basketball player, his picture quickly circulated online. he found his legs gave way. >> first thing i remember is seeing that -- a part of my hip was missing. it looks like, you know, you punched through something and it just kind of -- and it was just coming out here. >> reporter: knocked to the floor by the first blast, he was spared the impact of the second. >> now they are saying the second blast went off. that's where i want. >> reporter: a total strachblger saved him putting his legs up on a suitcase slowing blood loss before medics reached him. >> an african man came and dragged me to behind the column, one of the columns. crying went to the screaming because my leg wasn't following. i had to reach down as he was pulling my hand, i was holding my leg. >> reporter: across the atlantic, his wife sarah turned

on the phone and learned of the horror from friends' messages. >> i looked at my app. that's how we communicate. and i saw that he didn't have anything. and i saw from another friend, she wrote something eerie like, we're here for you if you need us. something like that. we're thinking of you. i'm thinking, why is she writing that? what does that mean? >> reporter: months in a wheelchair is ahead for this former athlete. a tough recovery even to walk again, yet love is all around. >> vanessa, our youngest one, wanted to know if all my boo-boos were covered with band-aids. the point was first survival. after survival was, okay, keeping the leg, and then, all right, if you stay alive and, you know, if you don't keep the live, at least keep one of them. >> reporter: and the hardest part --

>> why did i make it? yeah. kind of -- you don't feel bad. i feel proud that i was able to overcome it, but, you know, why was i -- why did i overcome it but others didn't? >> reporter: nick paton walsh, cnn, brussels. >> we certainly wish him well in his recovery and all those who survived. all the people that were injured that day in brussels. you can tune in later this week for the premiere of a cnn special report on the paris terror attacks.
