Unaccounted for. Authorities are working hard to determine if they could be among the 31 innocent People Killed or the 270 left injured. Police are desperate to locate the man you see here in the light colored jacket, who was spotted with two of the airport bombers. Its believed he took off before the bombs exploded near the u. S. Airline counters. Because of the bombs proximity to american airliners, some are now questioning if america herself was an intended target. Listen. I think its possible that it was that it was a proxy. Keep in mind, a lot more is going to become available, but the locations to me clearly were where americans would be. Shepard smith joins us live from brussels. Whats the latest there . Reporter good evening. I must say with no disrespect to the senator or anyone else, the speculation is unwarranted. The aisles where the bombers blew up their bombs were used by Different Airlines at different times on different days. Authorities say they are certain that these bombers chose those particular locations because thats where the lines were longest. You take the bomb to where the lines were longest, that causes the most injury and that was clearly their goal. The headline today is that the bomber himself, the man who made the ones, believed to be the one who made the ones in paris and here is dead. His name is najim laachraoui. They found his dna on the suicide vests in november in paris, and they found him blown up inside the airport at that terminal where the two suicide bombers carried out their mission. So the bomber, the man who made the bombs, and one of two brothers dead there in the airport. The other of two brothers killed in the subway when he exploded his suitcase. The one man still at large is a man for whom we have no identity, we dont know his name, what sort of participation he might have had and where he might have gone. Witnesses initially said he may have run out during the bombings, but now authorities lead us to believe that they are of the opinion that he left prior to the explosions, whether he chickened out, or just left and changed his mind, whether he realized his bomb wouldnt detonate. Those are matters for future news conferences. And further, authorities are insistent they believe some other unknowns also played a part in some way in these bombings. They have not given us any descriptions or reason that they have that to believe. They tell us theyre looking for unknown people and raids are being carried out across the city even as we speak. Those are the headlines here. I would say there are a number of investigations ongoing inside the neighborhood where they found that bomb making factory. And the taxi cab driver who led authorities to that house is being hailed as a hero here locally. He saw the pictures on screen, said that looks like the guys i took to the airport. Led authorities to that home and thats where they found 33 pounds of that explosive that was used in all of these bombings. Keep in mind, one pound of explosives is all they needed for the suicide vests in paris. Shepard, what do you know about this neighborhood, molenbeek, where were learning so many are becoming radicalized . Reporter the two brothers, khalid and ibrahim both grew up there and lived there for decades. Its neighborhood separate from the rest of the city. Different Police Officers there, different language there. They didnt cooperate well with the national authorities. Unemployment rate around 33 . A Young PersonsUnemployment Rate in the mid 40s. And varied suggestions from almost everyone there, its very hard to get ahead there. So you have that sort of an environment where people are looking for a way out and then in come the jihadis from syria saying we have a plan for you, we have a place that you can belong. Like a cult would, they become brainwashed. Now the task is to get the federal and local police and Community Organizers together change that culture. Shepard smith live for us in brussels, belgium tonight. President obama faces criticism for choosing to continue his overseas trip. And even attended a baseball game in cuba. The former cia director suggesting this was a sign that the president doesnt view the attacks as all that important. This is going to sound harsh, but i think its true. That wasnt a mistake, that wasnt weakness. That was policy. His going to the ballpark, and his spending less than a minute commenting on the attack. I actually believe in his heart of hearts, the president s policy is, that is not that big a deal. There are other things that are more important and that is what he was messaging. President obama says that is not the case. Ive got a lot of things on my plate. But my top priority is to defeat isil, and to eliminate the scourge of this barbaric terrorism thats been taking place around the world. Dr. Sebastien gorka is author of defeating jihad. Good evening to you, sir. Good evening. Thank you. So is this criticism of president obama not coming home following these attacks, is it warranted . Well, you just quoted a Career Air Force general, head of the Central Intelligence agency, and i tend to agree with general hayden. The statements made by the president smack of the mary antoinetteish attitude, let the people eat cake. Terrorism seems to be a distraction from his life of being a celebrity. He wants to be hanging out with communist dictators and going to ball games. Isis is simply not treated as a threat by this president or at least he doesnt give the impression that he really cares about our allies and the americans that were wounded. Lets think about one thing here the white house response to that, president obamas response is he said we let the terrorists win if we all stay home and dont go about our daily business and he said today, isis is his number one that is his top priority. Why is there a disconnect in what we feel versus what we see . These are just empty words. He said we have to unite to defeat the terrorists, but how . How are we going to defeat the terrorists while hes watching a ball game and giving interviews to espn . The fact is, we have to do something concrete. And also, it is the duty of the commander in chief to rally the people, to send a message that we will fight and destroy this evil scourge that is global jihadism. Its not enough to say, were on top of it. Remember, the day before san bernardino, the second largest attack on u. S. Soil after september 11, both the president and secretary kerry said, isil is contained and we are winning this war. This is not how you win wars. So what would an appropriate response from the white house be to this . Coming back home as soon as possible, making a statement from the rose garden or from the oval office to the American People about how we will not stand for this, who the enemy is, that theyre really evil and we will destroy them and to do something tangible for the belgians, for the people that need our help right now. To send a message. And most important of all, if you want to have the long game, if you read my book, this war will be won by our muslim allies in the region, and we have to help the egyptians and jordanians much more than we are doing today. So dr. Gorka, the Associated Press reporting today that isis has trained and deployed hundreds of their fighters to europe to carry out these terrorist attacks. We saw the state Department Today warn u. S. Travelers, if you go there, to be vigilant, to be careful where you attend like ball games. Where is this going . You dont have to hypothesize. Just look at the fact, my wife and i published a paper on the domestic isis threat. In the last 18 months, we have killed or we have arrested more than 95 people in america linked to isis. So the jihad is already here. Its not just in brussels, its not just in paris or in the middle east, it is here. They have the capabilities and they have an estimated 6,000 westerners who have been recruited by isis, who have western passports, including american passports who can travel freely. We must take this threat much more seriously. And Michael Mccaul saying today there are open investigations, isis investigations in all 50 of the u. S. States. So we thank you for joining us tonight, dr. Gorka. Thank you. My pleasure. As you heard, u. S. Investigators are looking into whether the terrorists in brussels were trying to kill as Many Americans as possible in those attacks. Chief intelligence correspondent Catherine Herridge has the latest information. Reporter sandra, based on the evidence so far in his classified briefings, the republican chairman of the House Intelligence Committee told reporters today he believes the terrorists in brussels were targeting americans. The bombs at the airport went off near the checkin desk for american and delta and detonated near the u. S. Embassy stop. And the congressman said, it doesnt seem to be a coincidence. If it becomes true that American Airlines and united and delta, that the explosive device went off there, when you couple that with the metro stop near the embassy was also targeted, those are two locations where a lot of americans can be killed. Reporter also today, the state department issuing a warning to americans traveling in europe. The terrorist groups are planning more attacks, possibly targeting sporting events, restaurants and transit systems, adding the threat is real and may be imminent. The travel alert reflects our assessment that given current information, we believe that daesh, al qaeda, and other terrorist groups continue to plan nearterm attacks throughout europe. Reporter the Associated Press is reporting tonight based on european intelligence sources isis has dispatched 400 fighters to europe. U. S. Government officials arent commenting on the number, but said between france, germany, and belgium, more than 600 citizens have traveled to syria and returned home. Sandra . Catherine, thank you.

That was bill bratton reacting to ted cruzs suggestion that Law Enforcement should be patrolling muslim neighborhoods in the u. S. To prevent terror. But with terrorists suggesting that the Islamic State has trained and sent 400 attackers to europe and with the state department issuing a travel alert for americans traveling to and around europe, cruz is not backing down. Trace gallagher is live in our west coast newsroom. Good evening, trace. Reporter good evening. During his comments on the attacks in brussels, ted cruz listed a number of counterterror measures, including we need to empower Law Enforcement to patrol and secure muslim neighborhoods before they become radicalized. Critics blasted the statement saying it amounts to a police state against muslims. President obama noted that cruzs own father fled exactly that kind of draconian policing in cuba. And Hillary Clinton said this. So when republican candidates like ted cruz call for treating american muslims like criminals, and for racially profiling predominantly muslim neighborhoods, its wrong. Its counterproductive. Its dangerous. Reporter clinton went on to say everyone should feel together in the fight against terrorism. Ted cruz responded. Watch. With all respect, people are fed up with the Political Correctness of barack obama and Hillary Clinton. Reporter and donald trump is siding with cruz saying he supports patrolling muslim neighborhoods. In fact, a President Trump would take more expensive action. The waterboarding would be fine, and if they could expand the laws i would do a lot more. You have to get the information from these people. I am in the camp where you have to get the information and you have to get it rapidly. Reporter but even the former doj lawyer that wrote the memos that approved waterboarding during the george w. Bush Administration Says what trump is suggesting is illegal. And he thinks trump is exaggerating. Trace, thank you. Joining me now to react, pete hegsath and carl higby, a former navy s. E. A. L. And supporter of trump. Carl, where do you stand on water boarding . I dont think its that bad. We get that as part of our training. Its miserable, but its not that bad. If we water boarded that guy we had in brussels, we might have stopped this attack. Its miserable but not that bad. But you actually say that waterboarding could have prevented these attacks in brussels. I can tell you not waterboarding didnt get us the information. So why not give it a shot. All right. Where do you stand, pete . Well, i dont have much of a problem with waterboarding if its going to get us the intelligence we need in realtime. The problem is the incoherence of what donald trump talks about. He says he wants to torture but his advisers say no, thats not what he means. Hes not grounded in a real understanding of what his rhetoric means. Therefore, he overcomplicates the situation. For the most part, carl and i agree. We would unleash war fighters, let them go and find the enemy and kill them. But his rhetoric is unhelpful. I think hes been real clear on that. Petes pamaking the argument that its more the delivery of the message. He wants to bomb the crap out of isis and if the laws permit, he wants to do much more than waterboarding. So donald trump and ted cruz appear to agree on at least one thing. Donald trump said late yesterday he agreed with ted cruzs proposal to target muslim neighborhoods, calling it a good idea. Have we found common ground, carl . I think we have. This is the beginning of donald trump bringing the Republican Party together. I think the message is all getting on board. Whats happening is people are coming around. Hes not targeting muslim neighborhoods, just maintain the level of police force in those neighborhoods. Pete, based on your experience, would this work, muslim surveillance . Well, it did work with the nypd before de blasio got rid of it. Youre talking about engagement, surveillance and intelligence. It makes sense. I know 100 of muslims arent terrorists but 100 of terrorists are muslims. Theyve got parts of cities where bombers are provided havens. Its just a preview of what america could become. So when donald trump and ted cruz talk about this, theyre ripping back the curtain, the false choice that so many of our politicians give us, that were forsaking our values if we target the enemy. Thats just wrong. Were at war right now and we should recognize it. Pete, you look at any country in the world where muslims are the minority, theyre screaming for rights. But where theyre the majority, there are no minority rights. So why are we letting them defeat us at our own game. So based on both your experience in the military, which is significant, are we having the right conversation in this country about how to combat this . I think the way to combat this is were going to have to go over and take the fight to them. The problem is our president with his limp wristed Foreign Policy has failed to define this enemy. Carl, youve been very vocal of your support for donald trump and you say many of your peers in the military support them, as well. Pete, who has the best plan that you have seen laid out by the president ial candidates to defeat isis . The guy who i felt like had the best plan was marco rubio, but hes not in the race anymore. Ted cruz has a coherent understanding of the enemy and he understands how to target the enemy. And isnt wildly vacillating to the extremes like trump does. We need to engage allies in so many different parts of the battle and i think ted cruz has a good sense of what it means to be commander in chief. But the debate needs to happen. Thank you to you both. Thank you. Another ugly turn on the campaign trail. This time involving the wives of the men, one and two in the gop president ial race. Thats next with that. Plus, catholic nuns are fighting against the obamacare contraception mandate, in what some are calling the biggest religious freedom fight since hobby lobby. This is not about us imposing any kind of restrictions on our employees. This is not about us denying them anything. This is about insisting that the government not impose its pressure on us to violate our faith. With hydro
