[Donald] Trump is underestimated greatly in terms of his understanding and comprehension of the great issues facing America. He understands trade. He's got businesses all over the world. He understands currency and how manipulating currency can be damaging to America.

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.

Some of my best friends are FBI agents.

I concluded that the trade agreements weren't working as promised, and was depreciating the wages and the manufacturing base, and the jobs of Americans, and that both needed to change, and Donald Trump was out there. So I went to his rally.

This [Gang of Eight bill (S.744)] is far, far too many low-skilled workers that are going to take jobs and pull down wages of people unemployed and underemployed right now.

Donald Trump foreign policy speech got good reviews, and it says we're going to defeat the people who are direct threats to us, but we're going to be a lot more cautious about getting involved in long-term, Wilsonian adventures.

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