My hope is that's something [Donald Trump] is thinking about, because not only is the president of the United States somebody that the entire country looks to for direction but sets the agenda internationally in a lot of ways.

We can't expect to solve problems if all we do is tear each other down. You can disagree with a certain policy without demonizing the person who espouses it.

The United States is committed to a regional order rooted in international rules and norms, including freedom of navigation, and the peaceful resolution of disputes. That's the only way to ensure our common security.

I have 90 percent or 95 percent support in the African American community and it's not sort of "Well, he's black, so it's okay. We're not going to say anything even though we're seething." And I hang out with a lot of middle-aged black women, and they're not casual in their support of me. There's a lot of love forthcoming. Partly because they understand the constraints of this society. They know that this is hard.

I think what will happen with Donald Trump is there are going to be certain elements of his temperament that will not serve him well unless he recognizes them and corrects them.

The sort of seeing cruelty and callousness of that sort from young people is heartbreaking.

I think it's useful to keep in mind I've been now President for over seven years and gun sales don't seem to have suffered during that time.
