We played all that rhetoric, all of the thing - the provocative inflammatory things [Donald Trump] said over the last year, does that all add up to buying him enough wiggle room with his base that he can get out and change his position like that?

This is a terrible year [2015] in a lot of ways. You have Paris. You have San Bernardino. But there was, if you remember the summer, there was that attempted terror attack on the train in France. There were two U.S. Marines, there`s one other guy. They were three guys who got up and who stopped that attack. Nobody died. They are heroes and they are my people of the year, three of them.

There was a change in tone in terms of the [Donald] Trump who showed up in Mexico City for this press conference.

Here`s what I`m curious about. For the president of Mexico, this man, Donald Trump, is, it`s probably not an understatement to say, despised by many Mexicans.

Looking to Donald Trump`s immigration speech can he hang onto his base if he softens his stance on the issue that got him this far?

To the extent anybody had heard of the [Charles] Kushner name at that point, it was a very tarnished name.

Chris Christie's rise in politics in New Jersey, in many ways, was built on his takedown of Charles Kushner. He got national headlines for that prosecution.
