What about those [Donald] Trump supporters out there and we've seen several incidents of this, with racially-charged intimidation of students and things like that? Doesn't President-Elect Trump have some responsibility to say something about that?

I think [Republicans] would really like to rip up that [Iran nuclear agreement] and get a new one, but that's going to be very difficult. You, of course, have Russia involved in that.

Secretary of State, maybe they [Republicans] would consider Steve Hadley for that job.

Soon the Oval Office will be his [ Donald Trump] office, his home.

You would have to say his number one accomplishment has been to inspire a sense of confidence in the country... That confidence, that optimism, not only gives President Obama a political cushion, but it could have a real world economic impact.

Protected by a no-fly zone, surrounded by protesters, Trump Tower is buzzing with intensity. The president-elect's family, loyalist advisers and wannabes all jockeying for position.

The man at the center [Donald Trump], soon to be the world's most powerful, now shoulders the hopes and dreams of millions of Americans, the fear and anxiety of millions more.
