Looking at these beautiful pictures of their smiles and everyone together, it really brings it home for people. When you heard about the attack and you knew your brother lived there in berlin for 18 year, did you everyone think my brother are could have been there . Yes, yes. When i first art heard about it on the news, i was at work, i had the tv going and i said oh, dear lord, i hope richard and peter were nowhere near the market attack. I just said a prayer and kept them in my prayers. And then the u. S. Embassy called my sister at 6 00 in the morning on wednesday and my sister called me to let me know. And then the embassy also called me to let us know that my brother was in icu and that peter had lost his life. Were all thinking with him, pee peter and your brother, wishing for the best. Our thoughts with all of you. Thank you very much. Lets talk more about this investigation. Lets bring in Paul Cruickshank look with phil mudd. And we also have a former cia counterterrorism analyst and former fbi investigator. Paul, you are learning new information about an anis amri. What is the latest . The new information is that back in december of 2015, amri was preparing to try to go and join isis, actually going on long 20 mile treks in order to shape up for the journey, but he wasnt able to travel. He had become frustrated by that. And then started talking about launching attacks inside germany. All of that being picked up by a Police Informant inside this network in germany and then transmitted to German Security officials. This recruit him Network Inside germany according to analysts believed to have been responsible for as many as 20 peoplehim Network Inside germany according to analysts believed to have been responsible for as many as 20 people joining isis. And so that is a rather large number of people. One of them, according to information in this investigative files rose to a senior level within the Security Status of the guard of isis, so there is strong kind of connections from germany within this network back to the isis high command. And of course we also know that there was Communications Going on between members of this network. And the external Operations Wing of isis. And phil, what is so stunning giving this reporting and how many connections there were, how long this was going on, how much they had already caught and the fact that they had tried to key port him. Knowing what we know, codo you still think there not a german failure . Ort him. Knowing what we know, do you still think there not a german failure . Knowing what we know, d still think there not a german failure . Any intelligence official has to scratch their head and say what happened here. Somebody who stated intent to conduct attack, somebody in direct connectivity with isis affiliates and people arrested by the germans, somebody who had an interest to acquire weapons. You put that into a mix and that in most Security Services rideses to the top. One question remain. If you choose not to pursue this person with all your intelligence assets, the examination has to be there were other priorities that you had that drew assets away, that drew your telephone taps away. And i have to hear an answer to that question before i make a judgment. We know they arrested four people in his circle. Chris, we have learned tonight that amri communicated with this terror cell in germany using an encryption app known as telegram, the same app widely used by the paris taerir attaca . How tough does not make it . Extremely tough. All these different ways of communicati communicating, encrypted ways, phones that are encrypted that manufacturers wont unlock. Law enforcement probably has never had a greater challenge in terms of the technical surveillance aspect what haof w going on here. We have done a lot here in the United States with outreach, but were still not quite there. There are still blind spots in the u. S. And one of the alleged paris attackers was hiding out for months in msafe harbor. He was only caught frankly by chance. It is likely that amri could be doing the same. The question becomes as the hours pass how much more difficult does it make it for authorities to find him if he has people helping him hide . That is tremendous true. One of the things is that he actually was caught in his own neighborhood. And somebody in his neighborhood actually dimed him out within 96 hours of the paris attack. And yet local police did not push that intelligence up the chain so they could actually, it. And so that is one of the difficult parts about this whole puzzle is that you actually have multiple law enforcement, multiple intelligence agencies all working together trying to sort out all these pieces looking for this 24yearold man across europe. And phil, isnt one of the big challenges, obviously the lack of communication and some of the infighting between intelligence agencies across borders between European Countries. They have said that that had been getting better, but could that be a challenge and create a real obstacle here for authorities in europe . You have to look at this as two levels. Day to day cooperation across europe, we have seen brexit vote, people are talking more and more about raising walls. I think cooperation is questionable across European Countries who want to protect the activities of their own citizens before those citizens commit a criminal act. But one lesson of the counterterrorism and intelligence business. Dead people bring Services Together band when you haand wh people, i think for the short term that forces corporation amongst Security Services who couldnt afford to be embarrassed. And why were four people in his network arrested in november, he wasnt, even though the n they knew he was talking about committing attacks. I have to leave it there. Appreciate the reporting tonight. Outfront next, why the suspect was on the radar of u. S. Officials for months before the attack. A member of the House Intelligence Committee joins us next.

New information tonight about what u. S. Intelligence knew about the man suspected of killing 12 people and injuring dozens more when he rammed a truck into a berlin Christmas Market. Anis amri was known to u. S. Until against before t intelligence before the attack. Ivan perez has been working his sources. So glad youre with us. What are you learning about what u. S. Officials knew and when . Reporter months ago german intelligence provided information on this suspect to the United States and the United States added him to the nofly list. Were told German Authorities identified him as part of a group of jihadist supporters operating in central europe, a network helping to recruit fighters to join isis in syria. And some were communicating with suspected members of isis in syria. What kind of assistance is the fbi and Intelligence Community here giving to the german counter parts to try to find this guy . They didnt know his identity for the first 24 hours. He could have gotten on a plane. Reporter probably not on a plane, but definitely could have gone through several countries by now, youre right. The fbi has a legal attache in berlin who is in touch with the germans, but there is a lot that they can ck they can ccan do to help. In france and bell fwgiumbelgiu were able to provide key assistance. But they also have to work with thensa. Intelligence agencies here in the United States and in europe are very concerned that isis still has some command and control capabilities in syria, they are still able to communicate and direct attacks in europe. So despite the pressure that isis is under in syria and iraq or perhaps even because of that pressure, more attacks are affected. Ivan perez, thank you. Outfront tonight, andre carson is the first muslim lawmaker to serve on the house. Given evans reporting, we know the suspect was on the radar of u. S. Intelligence for months. Hes now been on the loose more than 72 hours. Plenty of time to get far especially in europe where you have these borders where he can drive from country to country. Do you see this as an intelligence failure by the germans . I dont. I think that our Intelligence Community has been work overtime and not only capturing this would be individual, but dismantling copycat operations from occurring. During the Holiday Season, we know that the risk is heightened. We know that there are targets where there are Huge Population centers and where people go shopping. And so what is important is were encouraging people that if you see something say something. Not out of stereotype, but based off of suspicious activity. But german intelligence did see something. They third multiple times discussion about an attack within germany. They knew that a year prior around christmastime last year that he had been training with others in this suspected terror cell taking ten mile hikes to prepare to join isis in syria. All the warning signs were are there. Some of his fellow suspected bad actors were arrested back in november. How is this not a breakdown of intelligence . I think whenever you have intelligence and local law enforcement, there will always be flaws in the system. Its an ongoing process. I remember working in indianas department of Homeland Security and counterterrorism and counter intelligence, and oftentimes we would get information, a lot was very help fell aful and some no helpful. So were constantly trying to make corrections as we work to keep he people safe. The president elect previously in the campaign called for a ban on muslims entering the United States. He later called it a ban on certain countries. He talked about the use of extreme vetting. Lets listen to what he said where he had when asked if the attack in germany caused him to reevaluate his position. I know you couldnt see that, but he said you know my plans youll along ive been proven to be right 100 respect abo o100 . Do you agree he . I think its unfortunate. If you look at the program from 9 11, 2001,he . I think its unfortunate. If you look at the program from 9 11, 2001,e . I think its unfortunate. If you look at the program from 9 11, 2001, . I think its unfortunate. If you look at the program from 9 11, 2001, it has not yielded much benefit. Items its unpatriot tiic. We dont want to single out muslims. It will discourage a lot of talent coming from our country. A lot of folks that have started businesses, hired americans and helped to make our country the great country that it is. And so my concern is that we will fuel the flames of islamphobia with this kind of approach. It was a are morel horrible tragedy for us and bad on our image when we did it with the japanese. And its difficult to target someones faith because people drop out of a faith. So to base it on a persons believe, we know there are billions of muslims that are black respect white, european, african. Where do you stop with this. So i think were setting a precedent for a downturn in this country. As a lawmaker, how do you feel tonight ahead of the holidays seeing what happened in berlin about a potential attack here in the United States of a similar sort . Well, i think i commend our local law enforcement, state, federal and Intelligence Community for having brave men and women who serve in this capacity. Brave men and women who are of faith and even atheist who want to keep america safe. But are you concerned abo about im always concerned. I was concerned
