America has a critical role to play as the most powerful member of the world community.

When Donald Trump focuses on a fight with the press or investigating leaks but doesn't seem committed to standing up to what Russia is doing at home and around the world, that is of profound concern.

We know that Russia was involved in hacking our democracy. We know that the evidence or information is sufficient to warrant an FBI investigation of this. We are trying to do as much of this as we can in the public eye transparently. Obviously, some of it will have to be done in closed session.

We should be worried about protecting the homeland. I think that policy is changing, should change and will change.

We will not let terrorists change our way of life; we will not live in fear; and we will not undermine the civil liberties that characterize our Democracy.

We still have a problem here in this country of access to airports and airplanes [for terrorists].

If someone is brought in for an interview, for example, and is asked about their views on things, but has posted things that are completely contrary to the interview, frankly I have much more faith in what they posted than what they say during the course of an interview.
