Occasionally [Donald Trump] says things that are too strong and upsets people, and I think he'll work to do better on that.

We're going to build a wall. Donald Trump never said it's going to go from one end of the country, from the Gulf to the Pacific, and he'll use good judgment about that. And there are ways, through tax and regulation policies, that we can - and immigrant fees - that this could be paid for. I have not studied the details of it but, absolutely, I think that is possible.

We know that a ready amnesty tends to be an invitation to more illegal entries.

When I came up as a United States Attorney, I had no real support group. I didn't prepare myself well in 1986, and there was an organized effort to caricature me as someone I wasn't. True. It was very painful. I didn't know how to respond and didn't respond very well.

I think Donald Trump's history has shown that this was a very problematic thing. There were so many ways Iraq could have gone awry once we started, and I don't think most of us spend enough time considering the dangers.

[Donald] Trump has made this a big issue. He's leading in Ohio. He's leading, right up there in Pennsylvania, 1-point difference, and people are responding because the people's instincts are correct. This is what I believe.

How can we vote for a bill [S.744] that our own CBO says will reduce average wages in America for 12 years, increase unemployment for 7 years, and reduce per capita GNP growth over 25 years? A bill that will admit 30 million people to permanent legal status in the next 10 years? That will dramatically increase the annual immigration flow, and will double the guest worker flow?
