The race for president gets personal. Ted cruz facing off with donald trump. Even for donald, though, hes reached a new low. Its one thing to try and attack another candidate. Its another to thing come after my wife. Now another attack from trump this morning and what cruz said that may have been borrowed right from hollywood. And we do say good morning, america, on this thursday morning and we have breaking new developments at this hour in the hunt for those terror suspects in brussels. George is off this morning. You see david muir, he is anchoring live from brussels. Good morning, david. Good morning, robin. Great to be with you, as always. Youre right, there are several breaking developments after the terror attacks in brussels. Authorities are now searching for two suspects this morning. There had already been a massive manhunt under way here and a this morning, people patted down at random checkpoints as Police Search for the man in white from this surveillance video. Still not identified but on the run this morning and breaking now, word of a second man, captured on surveillance at the subway. We have obviously known about the bomber in the subway but this morning, they now say theyre looking for someone else from that very scene. And were learning more about the other suspect, two of them brothers, and now a failure of intelligence may have allowed them to carry out their attack. There were warnings. We have it you will covered this morning and gma news anchor amy robach has been in brussels from the very start and has the very latest. Good morning, amy. Thats right. Theres been a significant number of breaking developments this morning. The suspects in those paris attacks, salah abdeslams lawyer appeared in court just moments ago saying his client will not fight extradition to paris and he claims his client has no knowledge of the brussels attacks. Meanwhile, were learning so much more about those five suspects in this case. This morning, random security checks popping up all over this city. A sign of the new normal here. Authorities just announcing the search for a fifth suspect in the terror attacks, seen on Surveillance Footage inside the maalbeek station with Khalid El Bakraoui before he detonated. Investigators race to piece together the trail of clues left behind by the two deceased airport bombers. Belgian officials telling abc news they believe this man on the left is najim laachraoui, the bombmaker theyve been hunting since the november paris attacks. Police discovering his bomb factory in this suburban apartment. 33 pounds of socalled mother of satan explosive, chemicals, detonators and a suitcase filled with nails and screws and this man in the middle identified as Ibrahim El Bakraoui, an urgent call for a shared European Intelligence Agency after turkey admitted they deported el bakraoui to t year. The president of turkey says they warned belgium that the bomber was a terrorist fighter but says belgian authorities couldnt identify a link. Turkeys president confirming wednesday that hed been captured last june on the Syrian Border deported back to europe an flagged a foreign terrorist fighter, but Belgian Police only identified him as a common criminal. Police found what appears to be a suicide note on a laptop in a garbage can from el bakraoui. A desperate note that he was being in a rush, no longer knowing what to do in a bad situation and if he did not act immediately, he would be in a prison cell like him. Authorities believe him may be salah abdeslam, one of the suspects of the paris attacks detained last week after a fourmonth search. He is suspected of playing a role in the brussels attack prior to his arrest. That arrest may have caused the terror cell to panic and accelerate their plans. The number of those injured in mondays attacks is up to 300. Them, 61 people in intensive care. Four still unidentified as they lie in coma. Among the missing, kentucky couple justin and stephanie shults. It is a tense scene here in brussels as authorities continue to hunt for those two missing suspects and the airport here at brussels will be closed through saturday. It is still a crime scene as investigators comb through every detail to try and find more clues into finding these suspects and, david, you and i were out late last night. It was eerie. It was a ghost town. Police heavily armed members of the military and a few of us coming home trying to get a bite to eat but its obvious that brussels here is still at its highest threat level. I went into the subway yesterday late in the day and they were closing it early and they had armed guards at every checkpoint. You had to open your coats before you could get on the subway here so completely different city after these terror attacks. Of course, the bigger question now, how big was t cell . How many are still alive and possibly planning attacks and, robin, i know you have more on that. Well get back to you but abcs chief investigative correspondent brian ross joins us more on the missed opportunities to stop these attacks. There were 16 members that operated, 13 now dead. Belgian officials those two were only known as smalltime criminals but that wasnt true. One of them was wanted on terrorism charges with an interpol Red Notice Issued for him and the other was caught by turkish authorities at the border with syria and deported after the belgians were told he was a possible terror fighter. This cell operated for four months even after paris and again, and again Belgian Police let them slip by. Why all these chances . Authorities we talked to including senator angus king, a member of the Senate IntelligenceCommittee Says not only is there questions about their competence but discovered the belgians do information with other countries even agencies within their own country. There is serious infighting like disfunctional, inept, keystone cops. Even within. Even within their agencies they dont share with each other. Its sort of described what it was like in this country before 9 11. All right, brian, thank you very much. Back to david in brussels. Robin, thanks. Now to a gma exclusive from brussels this morning. My interview with the basketball player who played back in the states. His wife and two young daughters back home in michigan and played for oakland. He was hit in that blast and debris pouring down on top of him. The image of him laying on the floor went all over the world and for the first time this morning hes now talking. Telling me he was thinking about his young girls back home hoping they would not grow up without a dad. What did you see . I just saw i remember seeing an explosion, the first explosion near the pharmacy at the and i saw all these people running and when i got there, i was, you know, i think i blacked out for a little bit and i remember seeing two little kids to my right, you know, hands were up in the air and and then the whole the whole time i was just i told myself im going to make it. Im going to make it. Im going to make it and when i got in the ambulance i knew i was good. I guess thats the point where i was in the ambulance that i knew i was all right. But until then its i had no idea. So thats it. Im here to fight another day and so in the moment obviously in the most difficult moments about your wife and your kids . Yeah. Sorry. I just didnt want my girls to grow up without a dad, you know. Its all right. Have you talked to them. I talked to my wife. I think shes getting here tomorrow so its funny how many things you think of, you know, i started playing tennis with my oldest one, my 7yearold. Shes a hell of a tennis player so i was like, man. I got to get through this. You know, because she needs her coach and some of the things that go through your head. It may seem so trivial but it gets you through those moments. He kept telling himself while lying on that floor youre going to make it, youre gonna make it. You heard him say you think about the trivial things but theyre not the trivial things. He was saying i want to get home he can coach my daughter. I just began coaching her tennis. Now his wife is on her way to brussels. For all of those victims and their families who are suffering and struggling this morning, there are so many beautiful displays of support and strength throughout the city. Theyve cropped up even more overnight. I was walking here to our location, the amount of chalk written on the buildings all across the streets, everywhere you look, there are signs of love and peace and support and strength and the hopeful thing is that that helps this city and this world, frankly, heal from what just happened. The parents who brought their Young Children to the candles behind us while on the air this morning, a lot of the parents telling us that they wanted to help their children heal and one explain to my daughters and son that this is not normal. This doesnt happen every day and were Strong Enough to fight back, so a lot of families here, robin, trying to show that their city is strong, resilient and will come back from this. The strength of family. Thank you both. Well get back to you a little bit and, david, of course, will be anchoring live from brussels for a special edition of world news tonight. But now well turn to the other big story this morning. Here at home a massive blizzard slamming the west, michael is here and that story, that storm as you can see has buried colorado. It had buried colorado. Take a look at this picture. In two week, the Colorado Rockies were supposed to open a game ear at coors field and right now it looks a little hard to play baseball in that, robin, but this storm is really hit and paralyzed. More football weather than baseball weather. I didnt like that in football either. You know what, that storm is now taking aim at the midwest. So lets go to abcs Clayton Sandell who is there in denver for the latest. Good morning, clayton. Reporter take a look at these cars totally frozen into place, overnight the police and National Guard have been busy rescuing hundreds of drivers taken by surprise. This morning denver is recovering from being cut off from the outside world. The countrys fifth Busiest Airport completely shut down wednesday by a raging snowstorm and blizzard stranding thousands. We just heard that our flights canceled. Reporter forced to wait in long lines to rebook their flights. On the roads to the airport and everywhere else, drivers werent moving either. Hundreds of miles of major interstates shut down in wyoming, colorado and kansas, whiteout conditions leaving big rigs jackknifed and cars stuck. Ive seen half a dozen cars pulled over like this in just the last mile, all of them are abandoned and a lot of them are crunched. The seesaw from spring back to winter conditions came quick, gusting winds up to 60 miles per hour. Good grief. Reporter we could show you how the temperature plummeted from the 60s before the storm to the 30s but our thermometer got buried in more than 6 inches of snow. In the meantime, from ice to wildfire, strong winds are pushing flames and smoke across parts of oklahoma, kansas and texas. Some homes already lost and residents told to evacuate. And because of those fires kansas has now declared a state of emergency. Here in denver they tully set a snowfall record yet at just over a foot but a lot of people here especially the owners of these icy cars are hoping for a quick spring melt, robin. Im sure they are, clayton. Thank you. Lets get to ginger zee. Where is it headed . You can see stretching from northeast kansas through green bay, wisconsin, all the way into new england. Thats the snowy side but theres heavy rain and thunderstorms from just south of morning. The Severe Weather part of this, the hail, the accumulating hail almost 7 inches of which in north dallas moves to the east today and bang through windows like it did in texas in places like kentucky, nashville, tennessee, much of mississippi and northern alabama so thats where the severe part goes today. The winter storm warnings stretch all the way from maine back again into parts of iowa. Michigan, going to get hit with not only the snow but freezing rain and sleet possibilities. Ill detail more coming up. It is spring, right . It is spring. Just wanted to doublecheck that. Despite in that you see here. Okay, thank you. Now to the race for president turning into a war of words. Over wives. Republican frontrunner donald trump threatening to, quote, spill the beans on ted cruzs wife, now shes responding and abcs tom llamas is here with the latest. Good morning, tom. Reporter good morning to you. Namecalling has become the norm this Campaign Cycle but now the bickering is getting really nasty involving spouses and their looks. The gop race for president getting personal. Donald trump and senator ted cruz now in the middle of a wife war. It started when an antitrump super pac released this digital ad showing a nude photo of trumps wife. We had to blur it. The text on the image reading, meet melania trump, your next first lady or you could support ted cruz on tuesday. It was framed in such a way like it was really a terrible thing and it was sent to a Certain Group and i thought it was disgraceful and ted cruz knew about it. Reporter trump posting on twitter be careful lyin ted or i will spill the beans on your wife. Cruz posting back, if you try to attack heidi, youre more of a coward than a thought. When you read that, what did you think. I will say for donald he reached a new low. Its one thing to try to attack another candidate. Its another thing to come after my wife. Reporter was she hurt about it heidi remotely. Reporter even heidi cruz taking on trump. You probably know by now most of the things donald trump says has no basis in reality so we are not worried in the least. Reporter and cruz maintaining he had nothing to do with the ad and that it was, quote, completely inappropriate. But trump not buying it and standing by his threat. I wrote, i said, be careful because otherwise ill have to Start Talking about, you know, your situation. Reporter and cruz taking some heat for his choice of words. Some critics saying cruz stole a scene right out of the film the american president starring michael douglas. If done nandz wants to get in a character fight hes better off sticking with me because heidi is way out of his league. If you want a character debate, bob, you better stick with me because Sidney Ellen Wade is way out of your league. Sounds very similar. You can hear the reaction from the studio here. Cruz is a movie buff but its unclear if that was his inspiration, the fight not its really getting ugly. Overnight trump retweeting this image. The text reads no need to spill the beans, the images are worth a thousand words. Cruz replying donald, real men dont attack women. Your wife is lovely and heidi is the love of my life. Pretty bad, guys. Lets get back to the voting. The important stuff. The important stuff and the next one up is wisconsin about a week and a half. April 5th. An incredibly important primary so yesterday Ted Cruz Goss the endorsement of jeb bush and now wisconsins Governor Scott walker hasnt endorsed anybody yet. Says he will do it after easter but before the primary. Hes signaling, sounds like he may be endorsing senator ted cruz after easter. Well have to wait and see. Thank you very much. As for the current president of the united states, hes down in argentina. He is down in argentina and theres a video everyone has been sharing. The president and Michelle Obama visiting argentina right now and they were at a state dinner in buenos aires when two professional dancer talked the first couple on to the dance the obamas moves and brought 100 people to their feet, a standing ovation and lots of social media reaction and a tweet from southpaw comparing to his moves when he danced with alaskan schoolchildren in september. I think this is great and i think the tango is more his style. When it argue like you say when in rome maybe you could give him tips. Tango is the one were waiting on. I got some work to do. Lets talk about some of that snow and ice coming into new england too. Winter weather advisories and winter storm warnings that stretch all the way just north of portland, bangor, caribou, just north of the warm front, 41 boston, almost 80, d. C. Coming up we have an abc news exclusive. The jurors in that hulk hogan case now opening up about their decision to award him posted a portion of his private tape.
