Im katty kay in washington, Christian Fraser is in london. President trump in the last hour has been speaking to members of the Us Armed Forces in tampa, florida. This is his first addressed to troops as their Commander In Chief and he has been speaking in particular about nato. We have your back, every hour of every day, now and always. That also means getting our allies to pay theirfairshare, means getting our allies to pay theirfair share, they are means getting our allies to pay their fair share, they are very unfairto us. Their fair share, they are very unfair to us. They strongly support nato. We only ask that all of the nato. We only ask that all of the nato members make theirfull and properfinancial nato members make theirfull and proper financial contributions to the nato alliance, which many of them have not been doing. 0ur north america correspondent, nick bryant, is here. You were sitting with me in the studio, there is President Trump making what seems like a recommitment to nato, having once said not so long ago that nature was obsolete. One of the ringing phrase from the election campaign. And the fa ct from the election campaign. And the fact that he regards a lot of nato members do not pay their way and members do not pay their way and members are supposed to pay 2 of gdp to finance the defence. And the Secretary General of nato saying they should do exactly that. Yes, he is clearly saying america is not prepared to underwrite your defence any more, unless you stump up the cash yourself. He has also been talking about the threat of terrorism and of islamic state, it is very symbolic he is at centcom, the place that has run the wars in iraq and afghanistan and some of the activities against isis. And he said that terrorism has got so out of control, it has led to the point where the press does not even report on some of it. He said about the very, very dishonest media, dont even report on some terror attacks. He has recommitted america to the fight against islamic state. He has also spoken about this controversial Executive Order at the centre of this legal battle and he said he wa nts to this legal battle and he said he wants to allow people into the country who love america but do not seek to destroy it. So given everything that has happened over the weekend, and we will get onto the weekend, and we will get onto the legality of this Executive Order ina the legality of this Executive Order in a moment, but how much of the political problem is this for the white house at the moment, this Immigration Ban . It is a huge political problem at the moment because it has seemed to be rushed through, been worded imprecisely and it has been seen to open up the administration to this kind of legal challenge. At the moment, thejudges in the west coast particularly are holding, they are actually agreeing with the opponents of the order in saying that it should be stopped at the moment so that people from these mainly muslim countries can enter the country. So it has created a problem on that level, but there are many people, donald trump supporters, who are strongly behind this Executive Order and polls show the nation is divided but some of the nation is divided but some of the polls suggest there is majority support for this Executive Order, for what they see as donald trump doing what he promised to do during the campaign, to stop people from mainly muslim countries coming into the country. How did we cans events look to use in london . the country. How did we cans events look to use in london . I was picking up look to use in london . I was picking up on the papers over the week and i just want to show viewers what the papers have been looking at, the New York Times. The headline speaks for itself. Maybe you and nick could give us a view on this. Because the perception is from the papers i have read, this very small team around the president , in the view of the media, the perception is nine tenths of the law, they are getting it wrong. Well, all administration have turf battles when they first come into office. All the west wing staff are trying to get the influence of the oval office. It is different in this instance because these battles are being fought very angrily and very publicly on the front pages of some of the nations most influential papers, like the Washington Post and the New York Times. One person in particular is attracting a lot of attention, the chief strategist at the white house, steve bannon, very controversial figure, seeing as a very right wing figure, seeing as a very right wing figure who has the ear of the president. He was seen to be one of the key authors of the Executive Order, who wanted to rush things through. He has spoken about doing very big things very quickly. But over the weekend, there was an indication that donald trump is trying to slow down this Policy Making Machinery Hand to give more control to the person in the we st more control to the person in the west wing who ordinarily is the kind of chief enforcer for the president , the chief of staff, reince priebus. It also seems President Trump wants to have more of an influence earlier on in the Executive Order drafting himself. It seems in this instance he was presented with a document that he signed with a flourish of his pen and have not given it the attention that perhaps he would have wanted. So make you are a historian who has studied American History and political history and you know more about this than i do, but it seems to me that we are at a moment where something new is being tested, and thatis something new is being tested, and that is the ability of these populist movements together. If we see this as the beginning of that process , see this as the beginning of that process, and the question about this white house is, you have steve bannon, who is by nature a disrupter, an insurgent, can you marry that with more traditional governing processes . We have somebody like reince priebus, who is trying to put in Position Systems to make sure Executive Orders are vetted before they leave the white house, does that take some of the disruption out of it . This is the Power Struggle that at the moment is playing out within the west wing. Steve bannon has made no apologies, he is coming to washington to figuratively blow this place up, Thatis Figuratively blow this place up, that is what he believes that Donald Trumps mandate is from the voters, do not act like a normal politician ora do not act like a normal politician or a normal president , to defy those conventions. And donald trump has been doing that with the hurtling pace of the administration so far. But you get the sense that the president himself want to put the bra kes president himself want to put the brakes on a little and to give more authority to somebody who is more of an establishment figure. Reince priebus was the head of the gop, a washington insider, and the tension between those two people, bannon on the one side and priebus on the other, will be interesting to watch and it will be interesting particularly because it might define the nature of the Trump Administration and the nature of governance in this new era. Nick bryant, thank you very much. We are watching all this play out in real time on the front papers front pages. Lets get more about where we are on this trouble ban. Travel. With us is now is Doni Gerwitzmann from new York Law School hes an expert in Constitutional Law and theory. Where does the president stand, and the white house stand, on the legality of this right now . So, the president has defended the ban by pointing at something by the plenary power doctrine, it is a law that this Agreement Court has set up giving the Us Government wide discretion and authority to determine who can enter the country. In addition, the president is relying on the provision of the immigration and nationality act, where congress delegated power to the president to deny that any alien or class of aliens the ability to enter the country if the president believes they are detrimental to the national interest. So, in about four hours time, Thejustice Department has to go back to the appeals court, making its case for this suspension of the ban to be lifted. How can the Justice Department argued against the appeals court, which is saying, and thejudge the appeals court, which is saying, and the judge in seattle saying that actually, if we reinstate the ban it will cause chaos . The Justice Department i think will argue among other things that Non Residents located out of the United States do not really have rights under the constitution. They will argue for a very strong vision of Executive Power and a very strong vision of the power of the United States government in the area of immigration. They will argue that the Immigration Law is different in that the Us Government can do things to Non Residents located outside the us, that it cannot do to american citizens. When you have one party that controls the white house and one that controls the senate and the idea of those who favoured the constitution was that the court would be there to provide checks and bala nces would be there to provide checks and balances and it seems that in attacking thejudge, the president is undermining the hostage usual system. Without question. The constitutional system. There are a number of Emergency Brakes that framers put into the system to prevent the executive becoming a tyrant, doing whatever he wants. One major Emergency Brake is congress, which can always operate to check the president. In a situation where congress and the president come from the same political party, it might be that we will need to rely on the courts to play a much more aggressive role in telling the president noel. I do not think president noel. I do not think President Trump did himself any favours by personally going after thejudge in washington favours by personally going after the judge in washington over this decision. If anything, the judge in washington over this decision. Ifanything, i the judge in washington over this decision. If anything, i think it may have cost the judiciary to be more aggressive in checking him. So you knowjudges, you spend all your time with them, i will assume that if President Trump calls a member of the judiciary if President Trump calls a member of Thejudiciary Eight if President Trump calls a member of the judiciary eight so called judge, Thatis The Judiciary Eight so called judge, that is then going to lead other judges and potentially Even Supreme Court justices to judges and potentially Even Supreme Courtjustices to side with the judiciary, do you think . Judges are professionals and they will issue decisions based on the law. I do think the personal attacks trump has made members of the Judiciary Sort Of Change The Atmospherics surrounded the Executive Order. The issue ofjudicial independence and the ability of the judiciary to act asa the ability of the judiciary to act as a check on the president really moves as a check on the president really m oves fro nt as a check on the president really moves Front And Centre Won the president goes directly after a federaljudge. President goes directly after a federal judge. When president goes directly after a federaljudge. When the president. This is complicated, so thank you for unpacking all of that and one other update apple, facebook and microsoft are among 97 American Tech Companies to challenge President Trumps travel ban. The group has filed a legal document stating the ban affects operations and, in theirwords, Inflicts Significant Harm on business. The document was filed in washington on sunday. We have also been taking a look at the president s tweets. Hes been tweeting again, early morning, his time, about what he perceives as fake news. He said and he went on to tweet but it is begging questions, this, about his temperament, because we are getting used to him firing from the hip, and some of them, we can ignore but some of them seem a little bit petty. Some of these attacks against the fa ke some of these attacks against the fake news is entirely political and you wonder whether it is not symbiotic as well because donald trump is calling journalists from what he calls those fake News Organisations on a very regular basis. He speaks to the main White House Reporter from the basis. He speaks to the main White House Reporterfrom the new basis. He speaks to the main White House Reporter from the New York Times and the Washington Post and even speaks to cnn, which he also calls fa ke even speaks to cnn, which he also calls fake news once or twice a week and by the way, fantastic for their ratings, the New York Timess Subscription Doc mac the failing New York Times are doing particularly well i think the question here that is a more serious question is, what happens if donald trump is attacked by somebody more powerful than a news organisation, somebody for example with access to military weapons or even, god forbid, nuclear w if he says something on twitter, other countries will say, that is his view and we need to react. If it is china or north korea, how will he respond . It isa will he respond . It is a thing that worries countries away from the us, let me tell you. There are other leaders watching these tweets very closely. Here in the uk, the speaker in the House Of Commons, john bercow, has said he would not wish President Trump to address parliament. The speaker told the commons the president s views on immigrants and women were to him unacceptable. It looks like he has overstepped his mark. I would not wish to issue an invitation to President Trump to speak in the royal gallery. I conclude by saying to the honourable gentleman this. We value our relationship with the United States. Ifa relationship with the United States. If a state visit takes place, that is way beyond and above the pay grade of the speaker however, as far as this place is concerned, i feel very strongly that our opposition to racism and sexism, and our support for a quality for the law, and an independentjudiciary, are hugely important considerations in the House Of Commons. Applause lets go live now to westminster in london and speak to our political correspondent, eleanor garnier. You had better start for our international viewers, just setting out whojohn international viewers, just setting out who john bercow international viewers, just setting out whojohn bercow is. The Prime Minister has made it clear she wants the state visit to go ahead so, does he have it within his power to stop him addressing parliament . Everyone has been taken by surprise, even politicians who are in the House Of Commons as the speaker stood up. The speaker of the House Of Commons is basically like a referee in the House Of Commons. They are in charge of mps when they are in the House Of Commons and therefore, they are in a neutral position. That is why this is so unprecedented and it really is a sort of dramatic snub, if you like. He attacks the president has effectively being racist and sexist and for having a lack of respect for judges. There were even cheers, as we heard, when he made the comments in the House Of Commons. We know there has been this growing opposition to the planned state visit later this year, more than 1. 8 Million People have signed a petition outsi
