he's president until noon on january 20th. usually what that means is that a president-elect would avoid trying to box in the existing president, specifically on matters of foreign policy. the united states has to speak with one voice on foreign policy. in the transition that we have seen mr. trump criticize and in some ways undermine the one-china policy we saw him call on president obama to do one thing at the united nations, we saw this turn on nuclear weapons. isn't he kind of cashing checks that president obama has to cash? >> no, look, this is him preparing to be president. he's asked constantly what his position is on x, y or z and in the case of the nuclear comment, i discussed it with him directly. he's making the point that this is about nuclear proliferation in the face of rogue nations and regimes that are stockpiling weapons, it would seem. and all he's saying is his first priority is to keep us all safe and secure.
