The great and abiding lesson of American history, particularly the Cold War, is that the engine of capitalism - the individual - is mightier than any collective.

Nobody ever was fired for 9/11. Instead of firing the people who didn't do a good job, we gave them medals. The guy who did a good job, I don't know what happened to him. And what we did was we decided we'd just collect everybody's information. That we'd sort of scrap the Bill of Rights.

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.

To understand how Republicans lost the African American vote, we must first understand how we won the African American vote.

The people who get the ability to use force have to be watched carefully by civilians to make sure they don't use it excessively.

2007 was a long time ago, and events do change over long periods of time.

I think it's a huge mistake. I think regime change in Syria, and this is what - I've been saying this for several years now. In 2013 when we first went in, I said, you are going to give arms to the allies of al Qaida, to radical jihadists? That's crazy.
