On Twitter, Donald Trump has called me a "poor journalist, stupid, a very dumb guy, the dumbest political commentator on television, and the dumbest man on TV."

It is highly likely that one of the two of them [ Donald Trump and Ted Cruz ] is going to be the nominee. This is a - look here, what is this - what this is really is a prescription for remaking the Republican Party.

The professional permanent staff that lies right beneath them will still be in place, making everything work until the [Donald] Trump appointees start populating the offices on top of them.

Someone who traffics in much more than what Jeff Sessions said back then will be with the president every day in the White House as his senior strategist.

The [Donald] Trump transition team is already functioning as the worst transition team we have ever seen. And the good news is the slower they do their work, the better off we are.

I agree that we have to have the toughest screening and vetting that we can have, but I don`t think a halt is necessary. What we have to do is put all of our resources through the Department of Homeland Security, through the State Department, through our intelligence agencies, and we have to have an increased vetting and screening .

The screening in the United States is the toughest screening of any country in the world in terms of refugees, that accepts refugees. And of course there are those that don`t accept any, or ever have, no matter what kind they are.
