When I was secretary of state, I had to be responsible for getting a nuclear arms reduction treaty with Russia through the Senate. We needed, I think, 13 Republican votes to get to 67. I started working in the summer making just endless phone calls, meetings, bringing experts to talk to Republicans, and then we finally got it done at the end of the year 2010. So I'm excited to roll up my sleeves and get into the business of solving problems and making progress together.

It is essential that America's word be good.

I find it highly amusing that Donald Trump talks about "Make America Great Again." He doesn`t make a thing in America, except bankruptcies.

I think we can take back Mosul, and then we can move on into Syria and take back Raqqa.

Recently in Washington, unfortunately, we have seen examples of the wrong kind of leadership -- when politicians choose scorched earth over common ground, when they operate in what I call the 'evidence-free zone,' with ideology trumping everything else.

I think Barack Obama had the right idea [on negotiations with enemies], and the bottom line is that of course there have to be conditions. But, of course it doesn't do us any good to not talk with our adversaries.

We know that russians are deeply engaged in supporting Assad because they want to have a place in the Middle East. They have a naval base, they have an air base in Syria.
