I had met [Donald] Trump once before, when he testified before a committee that Tom Coburn - Senator Coburn - and I hosted, to deal with excessive expenditures to refurbish the UN building in New York.

It's perfectly reasonable and responsible policy for any nation to maintain its sovereignty, to protect its borders. And [Donald] Trump does not believe in ending immigration. He's never proposed that.

Voters are saying "I like this guy [Donald Trump]. He just might shake this place up."

When you suveil a person abroad, you don't have to have a warrant to do so. That has never been so they don't have the fourth amendment protection. On occasion, that person might call somebody in the United States, and if they're a terrorist, you really want to know who they are talking to. Maybe they're plotting an attack on the United States.

I believe that President [George W.] Bush was correct. I thought that Iraq had weapons of mass destruction, and I supported him steadfastly, and once we committed we should see it through.

Donald Trump is saying we're going to end the lawlessness at the border and we're going to push Mexico to do better. So there's been a reaction by the activist community to attack him.

In seven years, we'll have the highest percentage of Americans non-native born since the founding of the republic. And some people think, "Well, we've always had these numbers." But it's not so. This is very unusual. It's a radical change. And in fact, when the numbers reached about this high in 1924, the president and Congress changed the policy, and it slowed down immigration significantly. And we then assimilated through the 1965 and created really the solid middle class of America, with assimilated immigrants, and it was good for America.
