We had people coming to our Foreign Relations Committee and saying, "Oh, we need to arm the allies of Al Qaida." They are still saying this. It is a crazy notion. This is the biggest debate we should be having is is regime change a good idea; has it been a good idea.

As long as I sit at Henry Clay's desk, I will remember his lifelong desire to forge agreement, but I will also keep close to my heart the principled stand of his cousin, Cassius Clay, who refused to forsake the life of any human, simply to find agreement.

When we toppled [Muammar] Gadhafi in Libya, I think that was a mistake. I think ISIS grew stronger, we had a failed state, and we were more at risk.

40 percent of people who come to visit America on a visa overstay their visa and we have no idea where they are. On 9/11, at least 2 of the hijackers were here on visa. They were traveling back and forth to the Middle East. And we really had no idea where they were or what they were doing. And they were overstaying their visa. So there are problems I think in the immigration system that need to be fixed for our safety.

We should be proud that so many want to come to America, that it is still seen as the land of opportunity. Let's make it a land of legal work, not black-market jobs. Let's make it a land of work, not welfare. Our land should be one of assimilation, not hiding in the shadows.

It's a little different when you spend 30 years developing all these companies that we just ask [Donald Trump] to sell them. So I don't think that's a fair request.

[John] Bolton is so far out there, he`s advocating bombing everyone in the world.
