I said it was a mistake. It wasn't the best choice. But all my emails have been turned over to the public.

For 30 years, I've produced results for people.

I want to make college tuition-free for the middle class and debt-free for everyone else.

If they hear people running for - president... despite all the other problems that George W. Bush made after 9/11 when he basically said after going to a mosque in Washington, "We are not at war with Islam or Muslims. We are at war with violent extremism. We are at war with people who use their religion for purposes of power and oppression."

When people say, well, they disapprove, I'd like to know what the specifics are, because sometimes - and the president [Barack Obama] has admitted this - they may not feel like he's really explaining and understanding the emotion behind some of these fears [about Iran]. And that's a perfectly legitimate question for people to ask. But if you look at the results of where we are, I think there are some things I agree with and some things I don't agree with, and I think that's absolutely fair game.

I have stood up and I have represented my constituents to the best of my abilities, and I'm very proud of that.

I learned some valuable lessons about the legislative process, the importance of bipartisan cooperation and the wisdom of taking small steps to get a big job done.
