do you think it's possible? there have been some schizms between him and president trump before. do you think he's out of the loop? >> no, i don't think he's out of the loop. obviously the president is a disruptor. i think the trip to the dmz was a great optic and gesture that needed to be made. but at the end of the day a nuclear weapon in the hands of kim jong-un is not something that i support nor do i think many colleagues on both sides of the aisle support. >> i want to ask you what you say to critics -- widely i think no one is completely panning what the president did, but there's a big concern among people in this space that he's giving away leverage over kim by doing something like this, a photo op with north korea, which is something north korea really wants, without getting any concrete commitments on nukes. what do you say to that? >> well, you know, as the president walked away from the summit, i'm confident the president is doing what he needs
