Kirby: Trump’s Tweets Have Made It Harder Not Just for Tillerson But Also Mattis and Nikki Haley

EXCERPT:

KIRBY: "So this is a problem. I don't think the problem is, you know, who's got the better IQ. I think some of the president's tweets in particular have made it harder, for not just Tillerson, but for Secretary Mattis or Ambassador Haley, to do their jobs. I have said and I continue to believe that national security team around President Trump has done a commendable job trying to deal with the challenge in North Korea in particular."
