Deputy White House Press secretary, she will handle the briefing this hour. There surely will be plenty of questions about President Trumps reaction to the london attack. And his twitter rant today on the travel ban and on londons mayor, we may also hear more about the possibility of the president s using executive privilege to possibly try to stop the testimony of the former fbi director james comey who was fired by the president. Comey is set to testify thursday morning before the Senate Intelligence committee, his first Public Comments since being fired by President Trump. Lets get back to london where hundreds of Police Officers are trying to track down anyone associated with the deadly terror attack. As the mayor of london calls on the public to help police do their jobs. We recognize that terrorist actually want to destroy our way of life and harm us and attack us. Weve got to make sure we dont let them succeed. All of us have to Work Together to keep our city safe. The police with the right tools, but all of us giving the police information, making sure we stop youngsters from being radicalized and give them the information they need to reject these messages of poison. All over london those officers what are doing everything they can within their pow tore find out what was behind this attack but also to continue to keep our public safe. Our International Diplomatic editor Nic Robertson is joining us from 10 downing street and peter bergen is with me in washington. Police say they know the identity of the three attackers, they have not yet scleesrelease details. W why . They dont want the names getting out and perhaps having evidence changed or hidden. The police at the moment say that they are confident that they know who they are. This is a fast paced moving investigation that they have secured and seized significant quantities of evidence in the property raids theyve put into place. They also say theyve arrested 12 people. One of them has been released. The ages of the people range from 19 to 60. But at the moment the police are indicating that they will release the names of the attackers, but theyre not doing so far at this time. When the chief, the metropolitan police was asked earlier in the day was there any evidence that this had been somehow influenced from outside, the claim of course unsubstantiated climb by isis that these attackers were representing isis. She refused to comment precisely on this particular attack. She did say, however, that the threat coming in the uk at the moment from the three recent attacks, the thwarted attacks, the police look for an international connection, but at the moment she said broadly speaking and perhaps shes giving us a tip here about this attack t doesn attack, it doesnt appear to be directed from overseas. Weve get to get more details. We know the three terror attackers were shot and killed by police. The Police Commissioner also says theyre looking for possible accomplices. There have been about a dozen arrests as i point out. Talk a little bit about the search and the visible security that youre seeing in london. Increased Police Presence on the streets here just in routine patrols. Increased presence of armed Police Officers on the streets. Perhaps fewer people on the streets of london than we would normally see, although this is a normal workday. All the guidance from politicians has been, you know, dont be alarmed if you see Additional Police on the streets. Theyre here to reassure you. But for the investigation there is a lot going on that the public are not aware of. The police say that we can expect more raids and potentially more arrests. Those people that have been arrested appear to fall into the sort of category that weve seen police do in recent after recent terror attacks. They go to the premises where the attackers were last known to be living. Perhaps relatives. Perhaps friends or associates. In this case the age range include three sets of what appear to be adults, three males, three females. We dont know if these are the parents of the attackers, but these are the people that the police have detained so far. The police want to make sure that if there is anyone else, they say this was an isolated group in this attack, but if there are any others that have been influenced by the same people as any sort of indication that there could be a potential quick follow on copy cat is because we see that the momentum of attacks has increased over recent weeks. They want to make sure they get to anyone who might be associated with these men and thinking of a similar type of attack. The reporting in the british media suggests that these men have been associated with known radicals. Again, this is reports in the british media that havent been substantiated by the police but that would give rise in that context to a Police Concern that there would be other angry young men out there who might want to have follow on type of attacks. This is what the police want to make sure doesnt happen. Interesting. They have not yet raised, i dont know if they will, the threat level to the highest level in britain as they did after the manchester terror attack. Stand by for a moment. Isis as you know has claimed responsibility. So do you believe them . Do you think it was isis inspired . Isis directed . Or some other group . Or just a bunch of lone individuals . We dont know yet, but from isiss perspective, if theyve inspired an attack, its a direct attack. The Orlando Attack was the most lethal was inspired by isis. 49 people were killed in the guy nightclub in orlando last year. So for isis that was a success. Whether for them it doesnt really matter if its directed or inspired. In the case of the london attacks we dont know. My guess is it was certainly isis inspired. The Manchester Attack seemed to have been directed by isis. If you read the British Press as you have, nic has been going through it closely has well, it seems as if these three individuals, the terrorists who committed these crimes were themselves shot and killed by police may have been well known to local authorities. Well thats not surprising. The Manchester Attacker was known to local authorities. The guy who drove the car into the Westminster Bridge in march was known to authorities. Atino killed the 49 people in florida and they were known by the fbi. Whats atypical and is theyre not known at all. Everyone stand by. Well have much more on this story. Guys, thank you. President trump weighed in on the london terror attacks over the weekend tweeting out support for the victims of the attack but then the president went on the offensive criticizing the london mayor sadiq khan and unleashing a series of tweets about his travel ban just this morning saying among other things, people, the lawyers and the courts can call it whatever they want, but i am calling it what we need and what it is, a travel ban. The Justice Department should have stayed with the original travel ban, not the watered down politically correct version they submitted to the Supreme Court. The Justice Department should ask for an expedited hearing of the watered down travel ban before the Supreme Court and seek much tougher seek much tougher version. In any event we are extreme vetting people coming into the United States in order to help keep our country safe. The courts are slow and political. White house by the way also has a press briefing scheduled this hour. Well have live coverage of that. Sarah Huckabee Sanders will be giving the briefing instead of sean spicer, the press secretary. Shes expected to face lots of questions about the travel ban at fired fbi director james comey upcoming testimony. I want to bring in our senior White House Correspondent jim acosta and justice report laura jarrett. Jim, let me start with you. How senior the white house first of all responding to the president s significant number of tweets this morning, several of them so controversial . Very controversial, wolf. Obviously contrary to what white house officials have been saying for months. Weve been in briefings. Weve talked to officials over the phone who insisted time and again that the president s proposed travel ban was not a travel ban. They called it a travel restrictions. This executive order that would seek to block people from coming into the country from six muslim majority countries, they insisted up and down that this was not a travel ban and of course the president tweeting this morning that it is a travel ban, that he wants the Justice Department to seek review at the Supreme Court and have it reinstated. Obviously that is going to cause headaches here at the white house in just about half an hour from now when sarah Huckabee Sanders briefs reporters. Shes obviously going to be asked about those tweets. The president s top officials have been pressed on this all morning long. Take a look at sebastian gorka, one of the Top National Security advisers. He was on cnn new day. Heres how that exchange went. The policy of the media, chris its social media. Its not social media. Its his words, his thought. Its not policy. Its not an executive order. Its social media. Please understand the difference. So se bas dtrying to make th this is just social media. Kellyanne conway was on the today show accusing the media of being obsessed, she used the word obsessed with the president s tweets. Very interesting to point out her husband, George Conway, who withdrew his name from consideration for a Justice Department official at the end of the last week he tweeted criticism of the president s tweets regarding the propose add travel ban. These tweets may make some people feel better but they certainly wont help. Five votes at the Supreme Court which is what actually matters. Sad. George conway going to so far as to use some of the president s vernacular. This is a headache for the white house. It seems like whenever the president tweets its a headache for the white house and its going to be one yet again in about 20 minutes from now. That tweet from George Conway pretty surprising given the fact his wife works for the president and he was under consideration to become the solicitor general over at the Justice Department. Pretty surprising that he goes ahead and criticizes the president like that. The white house has asked the u. S. Supreme court to rule on this revised second version of the travel ban. Does the president s tweeting about it this morning jeopardize a white house case . Well, litigating this case via twitter complicates the president s Legal Defense on two different fronts, wolf. First is from a substantive standpoint. Lawyers at the Justice Department having working hard, bending over backwards to draw a distinction between trump statements preand post presidency because the prepresidency statements talk about muslims and that was a problem in court. But these series of tweets arguably show thats a distinction without a difference because the president has no apologies for what he says before and he is essentially throwing his own lawyers under the bus for being, quote, too politically correct. The other issue is timing. Hes tweeting about this case during the exact time that the Supreme Court is deciding whether to even take it up and the other side is crafting their briefs right now. So by calling it a watered down version, hes now handed the other side arguably another piece of evidence to suggest the changes between these two executive orders were not made in good faith, wolf. Were standing by, sarah Huckabee Sanders is going to have the press briefing coming up shortly. Were getting some breaking news. I want to go back to london. Nic robertson is on the scene. I take it were getting some of the names of those involved, the names of the some of the terrorists. Is that right . Thats right, wolf. The police had said they were going to name them. What were getting are the names of two of the three attackers. The police said all three were shot dead. Let me just read you here what we just had from the police. The two men, kareem and rasheed, both from east of london. More details here. Kareem, 27 years old, born the 20th of april 1990 was a british citizen who was born in pakistan. Rasheed, 30 years old, born the 31st of july, 1986. Had claimed to be morroccan and libyan. This is a man whos given a different date of birth here as the 31st of july, 1991. So one of the individuals has two aliases. Has claimed a different nationality from what the police have here. One of them a British National but pakistani origin. We can also add in what weve learned from irish police that they are helping British Counter Terrorism Police with connections to one of the attackers to time spent in ireland by one of the attackers. Its not clear if its one of the two named or the third person yet to be named, wolf. Well wait for that third name to come up. Just moments ago we heard from the mayor of london spooking out on this. Listen. As the mayor of london, i want to send a clear message to the sick and evil extremists who commit these hideous crimes. We will defeat you. You will not win. [ applause ] sadiq khan of london. The mayor of london speaking out at a vigil thats under way in london. He has been severely criticized by President Trump in a series of tweets. Well have much more on that coming up as well. Once again, were oem moments away from a must see White House Press briefing. The president s terror attack tweet storm and whether hell use executive privilege to try to block the fired fib director james comey from testifying thursday in the russia probe.

Today the deputy White House Press secretary sarah Huckabee Sanders instead of sean spicer will be taking questions from reporters. Shell likely be asked about the flurry of tweets the president wrote this morning on his selfdescribed travel ban. Well bring you that briefing live once it starts. Thats coming up later this hour. The white house also facing serious questions on how theyre preparing for the fired fbi director james comeys testimony this thursday morning in front of the Senate Intelligence committee. Will the president assert executive privilege . White house counselor Kellyanne Conway was asked this question this morning. Does the white house consider it a possibility that they would try to prevent the testimony by asserting executive privilege . Is that an open possibility . The president will make that final decision. Joining us now to talk about the limb teits of executive privilege, eric. Thanks for joining us. You dont believe he will exert executive privilege because you dont believe there will be of of a case is that right . He has no case. It is shield to protect the administration from assaults of congress. Here we have a private citizen who wants to talk. So it will be completely unprecedented. So why do you think the white house is not flatly saying of course the president s not going to exert executive privilege. Theyre leaving that hanging. You just heard Kellyanne Conway, sean spicer the other day. Its an open question they havent flatly ruled that out. Have you ever seen donald trump give something up for nothing . I think he wants to play this out as long as he can and then try to look magnanimous. There are other ways he can prevent him from testifying, namely to convince the republican chairman of the Senate Intelligence committee to call off the hearing because the president doesnt want that testimony to come up. He certainly could, wolf. He could try to invoke executive privilege, make a big show of it. And then chairman burr could say im shocked that james comey wants to discuss such private matters and then pull the hearing. Knowing richard burr, i dont think that strategy is going to work. Another strategy, he could just say to james comey dont do it. You were part of the administration, this is executive privilege. And then co
