I'm not going to quit. Why should I quit? This country is worth fighting for.

A psychologist once told me that for a boy being in the middle of a conflict between two women is the worst possible situation. There's always a desire to please each one.

I do agree that in particular, Turkey and the Gulf nations have got to make up their minds. Are they going to stand with us against this kind of jihadi radicalism or not? And there are many ways of doing it. They can provide forces. They can provide resources. But they need to be absolutely clear about where they stand.

A president of the United States should not have a racist at his side - unacceptable.

When I was in the Senate, I had a number of trade deals that came before me, and I held them all to the same test. Will they create jobs in America? Will they raise incomes in America? And are they good for our national security? Some of them I voted for.

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 want to congratulate Senator [Bernie] Sanders for the extraordinary campaign.... He has spent his long career in public service, fighting for progressive causes and principles, and he has excited millions of voters, especially young people.
