the new acting replacement, patrick shanann, he takes over tomorrow.resident apparently still kind of discussing this serious strategy here. this is not really shanann's area of expertise, dealing with these type of military matters. how big a challenge is this going to be for him? >> that's exactly why there should have been a longer transition period. during his transitions from a secretary to an acting secretary, even if it's a deputy, typically there's a handover of information. what the secretary knows, he tries to impart on whomever is taking over for him. trying to do that over the course of just a few days is literally impossible, especially when you have a secretary that's on the outs with the president and is trying so rapidly to wrap things up. it's unclear who is really leading discussions on the responsible drawdown of troops on syria, what timetable they're going to be following and where they're going to be relocated to and who else is going to pick up pieces of the mission. >> you know, there was a sense that both general kelly and gene

watts was asked three questions during his polygraph, including whether he physically caused his wife shanann to disappear. he said "no", but the test indicated he was lying. later, investigators got him to confess that he killed his pregnant wife and his two young daughters, bella and celeste. earlier this month, watts was sentenced to 'five' life sentences without the possibility of parole.

it does come now as now the incoming, acting secretary, patrick shanann, his first job may be to figureident trump really wants to do about withdrawing troops from syria. is it on pause? is it happening rapidly? no one really seems to know. and as he begins his tenure actually tomorrow. mattis left the building actually today. we're not sure if he's actually going come back at this point. and he left behind a message to the troops, which has just perhaps a little bit of a dig at president trump's isolationism. let me read part of it to you. the secretary saying, "our department's leadership, civilian and military, remains in the best possible hands. our department is proven to be at its best when the times are most difficult. so keep the faith in our country and hold fast alongside our allies allied against our foes." alongside our allies. that is secretary james mattis in his final hours in office. once again endorsing alliances and coalitions he believes very strongly that is essential to u.s. national security. ryan? >> and as jim mattis leaves this post today, barbara, i want to ask
