great deal of regard for who was there. now, we're in a situation where, obviously, the president's going to have to step up and there's grave concern as to what direction that he might be going, so we look to who's going to be put in next. erin, you said it. the letter that mattis put together gives a road map of the areas where i think everyone's now going to be looking, to that next person for clarification, what are the differs between mattis and the president with respect to china, russia, as he said, malign actors. and also, treatment of our allies and how do we look to the person who's coming in next to ensure that we have very secure policy for national security. >> i understand part of your job now is to come on now and calm people down and say, woo ee're g to find someone else and i think every american will hope that we will. there's nothing more important than this job but we're at this moment where someone with 40 years of experience, a four star general general, one of the single most respected people in the american military is saying the president won't listen to anyone around
