I want to start with you since i know the briefing just wrapped up there and you were throwing questions to all of those officials. Sum up what you learned over the last hour. Reporter so, quite a bit, i think. It was a newsy briefing with h. R. Mcmaster and nikki hallie here and lets run through the top headlines. Number one, on north korea, nikki haley addressed the dominant issue heading into the United NationsGeneral Assembly next week talking about how she believes that the sanctions that have been put in place already in fact are a big step and just the beginning despite President Trumps comments that secretary of state tillerson agreed with apparently of a small step and she said something i think was interesting raising eyebrows and said im happy to kick it over to secretary mattis if Diplomatic Options are not working and heard the followup of i believe the Washington Post reporter saying do americans need to be prepared for military action with north korea and the possibility of war. The note, both officials talked about how both haley and mcmaster talked about the importance of giving it sometime to let the impact of the sanctions sink in. You are hearing a lot of Foreign Policy over the next week given the schedule laid out by general mcmaster for President Trump. Each day meetings with foreign leaders at the United NationsGeneral Assembly in his speech the first speech he will be giving them he is going to be hugging some people and slapping some people according to nikki haley, verbally, of course. And other than that, didnt reveal much about which nations he can talk about. We can assume iran, venezuela, north korea and others but we wont know. Its written. Other headlines, Scotland Yard tweet raising eyebrows. H. R. Mcmaster said the president was not referring to the specific incident in that tweet when he said that this individual or individuals were in the sights of Scotland Yard but referring broadly to terror incidents and terrorism. This did come up in that phone call with Prime Minister may that happened looking at the watch, a couple of hours ago between the president and the Prime Minister. The readout officially from the white house was that both pledged the president pledged close cooperation after the terror incident and then the other i think issue that came up was this espn sports caster commentator who called President Trump in a tweet essentially a white supremacist. Sarah Huckabee Sanders said that should be a fireable offense and theres followup on that in particular regarding whether thats appropriate because the president himself tweeted that this was an issue. And so, theres some back and forth with the press secretary about why the president tweeted that. What she meant by that. She sort of said, well, i was talking about a private individual and not a company and you heard that exchange there. So, monologue over. A lot of headlines out of the briefing today and more to come next week. Thanks. If you could stick around for a second, i want to ask hans, she mentioned secretary mattis and the them saying essentially, hey, diplomacy might be over here and time to turn this north korea crisis over to d. O. D. Whens the view of the pentagon . The view of pentagon is diplomacy is preferred course of action. You know, a lot of ways i think the most important thing we heard in the briefing is what we didnt hear and we did not hear any sort of announcement, any sort of telegraphing that the u. S. Is going to press for additional sanctions on north korea. And that we heard from nikki haley and heard from general mcmaster almost contradicts what we heard from secretary tillerson overnight which was that the sanctions that were passed and implemented on monday, this 30 reduction in fuel was the floor, not the ceiling. I heard from nikki haley there a lot of floor talk. I did not hear any aspirational, any goals, any indications that theyre pushing for additional sanctions. As they said, it several points, they want to see how these sanctions continue to work. Now, just real briefly on sort of the hinting and the glib responses of kicking the can down the road to mattis. A lot of ways, the posture hasnt changed. Diplomacy first. If that doesnt work, they have military options. Theres a slight change in tone and tenor there and the policy remains the same. Thats diplomacy first and we always have options. Guys . Yeah. I noticed that mcmaster was asked what went on in that call that the president had with theresa may. He said i wasnt on the call. Is it unusual for a National Security adviser to not be in on Something Like that and tell us anything about the relationship thats currently going on between the president and his National Security adviser . Reporter always a tendency to want to read tea leaves and i think that was unusual given that the National Security adviser might be in on the phone calls and discussions. I need to go do more reporting on why that was the case. I dont know what the generals schedule was today so well follow up with you. Any indication to hear more from the president . Well, yeah. Normally retracts the remarks on twitter making them. Heres the thing. I dont know regarding the Scotland Yard issue with the Prime Minister particularly because if they discussed it there might be a sense inside the west wing, hey, let it lie and move on and hearing from the president checking my watch in about an hour and ten minutes or so when he is over at joint base andrews for the as hans is well aware, the air forces 70th anniversary celebration. An air show and he will be there with members of the air force and i would not be surprised to hear from him regarding the threat of north korea. Seems like an appropriate or natural setting for him to bring it up and watching for that later on in the afternoon. Hallie jackson at white house and hans nichols at the pentagon, thank you for your time today. Joining me now is republican congressman kissinger from illinois. He served in the air force in both iraq and afghanistan and is still a pilot in the air national guard. Great to see you. Thank you for taking time today. You, too. You bet. Do you think that the launch of north korea was a direct response to the sanctions leveled against north korea on monday . Its hard to tell without actually asking kim jongun. We expected launches any way prior to the u. N. Sanctions and i think whats obvious here is hes going to continue to play a very dangerous game and that game is not just developing an operable Nuclear Fleet and something thats important to note, obviously, but willing to flex muscle and frankly fly a missl over an ally of the United States. What would happen had that missile failed mid flight and landed in japanese territory . What happens if he shoots a missile toward guam . This is a very dangerous, intense situation and dangerous intense man and so i think these u. N. Sanctions are good. Its a good start. Or i guess a good escalation. But at the end of the day, we have to pray and hope and do everything we can to make sure this economic stick works. Otherwise, i fear the only option is the military. Congressman, what is your level of confidence in the president s ability to handle the tension in this situation . I have talked to a lot of colleagues and to leadership aides and even among republicans theres been a lot of nervousness about the bellicose language, tweeting and seems theres a sense that the u. S. Government as a whole led by President Trump has gotten a little bit calmer and more capable. Do you agree with that, or do you still have concerns about the president s willingness to kind of fire off tweets at will when it comes to this kind of a potential Nuclear Crisis . Well, when it comes to typically on International Policy and twitter, im not a huge fan but that said weve tried this idea of walk softly, carry a big stick for 20 years coming to north korea. And if speaking softly doesnt work, ultimately, the answer is a stick. Esque lating the rhetoric to make it clear theres a military option, military options and many cases using language to make that clear is what makes diplomacy effective against an adversary. There are two instruments of power working in conjunction with each other so i dont have a problem, frankly, with some of the president s rhetoric on this because i think hes making clear to kim jongun and china and russia this is serious and we are taking this seriously and last thing we want to do and willing to defend our people and homeland is to use the military option. So speaking of of twitter, i do want to ask you about the terror incident in london happening earlier today. The president s tweet this morning, he said these are sick and demented people in the sites of Scotland Yard and set off anger of british officials, including the Prime Minister may. She said it wasnt helpful. Take a look and then well talk about it. Prime minister, donald trump has intervened to say it was carried out by people who Scotland Yard had in its sights. Does he know something we dont . I dont think its helpful to speculate on an ongoing investigation. As i have just said, the police and Security Services are working to discover the full circumstances of this cowardly attack and to identify all those responsible. And in the white house briefing, they just tried to clean this up a little bit when they were asked if the president should have done something differently here. Do you think that he should have approached this this way . No. Its what i was referring to when i said the twitter issue. I think thats the perfect time to tweet that, you know, the thoughts and prayers and resources of the United States of america stand with the people of the uk. I think to cast blame early on is absolutely the wrong way to go. But that said, calling them losers and, you know, sick individuals, these isis members or terrorists, i fully agree with that and whats important now is the western world, uk, United States and frankly all freedomloving people to make it clear it wont stand and liberating terror of isis, you run counter the narrative of a prophesied caliphate because thats not supposed to be defeated in combat and they are right now. I think he is missing an opportunity to make it clear that we all stand together with our friends. We are making progress against the terrorist groups and frankly this is a fight of our generation and last probably as long as im alive to some level and its unfortunate but its a reality i think we have to accept. Republican congressman of illinois, thank you for taking the time today, sir. Any time. You bet. Lets turn now to london where the Terror Threat level raised to severe after the attack we have been talking about all day. A bucket bomb detonated on an underground train. The device exploded 8 28 local time on a crowded commuter line. 29 people were injured but none of the injuries are life threatening. Authorities calling the explosion a terrorist incident. After first tweeting about the attack, President Trump said this earlier today at the white house. No, its a terrible thing. It just keeps going and going. And we have to be very smart. We have to be very, very tough which perhaps were not nearly tough enough but that is just an absolutely terrible thing. In fact, im going to call the Prime Minister right now. Nbc newss keir simmons joins me now from london. What is the latest in this investigation . Reporter well, i think tonight here as night closes in, we are beginning to get a picture that there are quite a number of people who very likely might not be with their family this evening if this crude bomb as it now appears had fully detonated. Our security analyst duncan garden, his sources telling him that the detonator went off in this improvised explosive device but the main charge did not. And that had it gone off what youd seen on that subway car would have been far worse. Hes also getting suggestions that it was on a timer rather than it was remotely detonated and that is somewhat different to the kind of attacks we have seen in europe in recent years where quite often its suicide attacks. Does that give the police some kind of an insight into who this was . Somebody that doesnt want to kill themselves trying to kill others. Perhaps so. Certainly theyre searching through the subway which is just along the street here now and searching through the security footage on the subway and on the subway car. That security footage on the london subway now is much better than its been in the past so they should be able to go back and find where whoever it is walked on to the car with this improvised device and from there begin to try to identify who he is. As of now tonight here in london they do not have anyone under arrest. Can i ask you about the Prime Ministers comments . Theresa may known to be critical . Reporter well, she is known for being pretty tough. Icy you might say. I mean, it was quite understated the response to the question. Diplomatic. But i think thats what counts in you know, in British Culture if you like as a rebuke to the president. We dont know if she was more forthright by telephone but the british have been pretty clear with the u. S. About their unhappiness of u. S. Intervention of an investigation going on like this. I would just say this and i think it reflects and spoken to people in Scotland Yard and not just a question of i guess feeling insulted. I think its also to do with that as i mentioned, right now, there is somebody out there who carried this out. We dont know who that is. We dont know how much pressure theyre under and for the president to suggest Scotland Yard could know it could affect the hours that play out and important to keep in mind. Nbcs keir simmons in london, thanks so much. Some of the president s biggest backers are saying so long. Even ann coulter whose book is titled in trump we trust. She tweeted today calling the president a sellout. If he keeps working with democrats on daca. And if he gives up the wall, will the base jump ship . When this bell rings. It starts a chain reaction.

Find it in a subaru crosstrek. I think you could see the emergence of a primary candidate from the right challenging donald trump. I think somethings going to have to be reversed here with this president s policy or itll just blow up his base. I mean, this was a straightup promise all the way through his campaign. He will get creamed on this. If this goes down the way i fear it will go down, mark my words. This will be an electoral nightmare for republicans. Iowa congressman steve king, laura ing gra ham and all reacting to policies that President Trump and congressional Democratic Leaders have reached a deal on daca while it only looks like they agreed on the outlines of a potential legislation thats not stopped some of the president s most ardent supporters of turning against him and a few gone so far to post pictures on twitter of burning make America Great again hats. Yikes. Thats an image. Joining us here, Timothy Obrien, editor of Bloomberg View and author of the trump nation. And from washington, the Washington Post political reporter amber phillips. Thank you so much for being here. Tim, i want to start with you. First, do you think that this is going to become an existential problem for the president , the pictures of the hats burning is a switch from the campaign. Well know at the midterms. Right . What i think hes done now is sown the seeds for real problems with his base because hes flip flopped on som
