I have not supported same-sex marriage. I have supported civil partnerships and contractual relationships.

I don't in any way underestimate the difficulties, because it's only gotten harder. But I do think you just have to go into politics with the attitude that you're going to speak clearly and authentically about what you see the country needs...and seek out whatever possible partners you can, even in the other party. I've looked at successful presidents going back. Some of our most successful governed through periods when their party was in charge, and when the other party was in charge. There's no magic formula.

[The Republicans] all want to see women's rights eroded and for abortion to become illegal again.

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.

Sometimes, opening up your eyes and realising what you have - no matter how little you think - helps you find yourself.

We are not putting ground troops into Iraq ever again. And we're not putting ground troops into Syria. We're going to defeat ISIS without committing American ground troops.

We need American Muslims to be part of our eyes and ears on our front lines.
