I think what the president [Barack Obama] understands, and what he's trying to do, is that we have to support the Arab and Kurdish fighters on the ground who are actually doing the fighting.

I support the Second Amendment. I lived in Arkansas for 18 wonderful years. I represented upstate New York. I understand and respect the tradition of gun ownership. It goes back to the founding of our country.

I think wherever we can cooperate with Russia, that's fine. And I did as secretary of state. That's how we got a treaty reducing nuclear weapons. It's how we got the sanctions on Iran that put a lid on the Iranian nuclear program without firing a single shot.

A group of national security experts, military intelligence experts, issued a very concerning statement about Senator Bernie Sanders's views on foreign policy and national security, pointing out some of the comments he has made on these issues, such as inviting Iranian troops into Syria to try to resolve the conflict there; putting them right at the doorstep of Israel.

When I spend my time out on the campaign trail, it's usually about what I can do for somebody else. I don't like talking about myself, I don't like the whole atmosphere of how people are judged in American politics too often as to what you say instead of what you do. And so for me it's always about what can I do for you? How can I help you?

Part of diplomacy is to open different definitions of self-interest.

I feel like my political beliefs are rooted in the conservatism that I was raised with.
