Donald Trump is a great listener, and he's a good challenger. He doesn't come across as a person who thinks he knows it all. In fact, he once told me he has had lot of things to learn.

NATO was formed post-World War II. We're a little bit more than a half-century old. Do we want NATO to go on for another half-century? I think that the answer is, sitting here today: I don't know. If I had to bet on it, I would say, yeah, we have to have these alliances going forward and see who's going to pay for them.

Trump respects people who are selfish about their country. Putin is a guy who is very selfish about Russia and about the Russian federation, and he understands the history of his country. You can't say, "I don't like you." You've got to respect him. He's a world leader.

One thing I agree with Donald Trump on is, there's something going on in the Muslim world.

The United States should not have to intervene in every single problem around the world. The voters of this country are reacting in a very big, broad way to Mr. Trump. They are frustrated by lousy decisions made by both George W. Bush and Barack Obama. Look at the mess we have.

I think we have such a political cesspool in America right now.

I do care about the direction of America.
