I think it is an imperfect arms control agreement. It's not a friendship treaty. But when America gives her word, we have to live up to it and work with our allies.

When I speak to students about the Civil Rights Movement, I say that it is impossible to stop a determined movement that is captivating the American consciousness. I think the candidacy of Sen. Obama represents the beginning of a new movement in American political history that began in the hearts and minds of the people of this nation. And I want to be on the side of the people, on the side of the spirit of history.

I would say to a young person: continue to study. Study what is taking place in your community, in your neighborhood, maybe at your school.

I remember being at the church a few hours after the church was bombed in Birmingham, the 16th Street Baptist Church. It was very hard and very difficult to stand on that corner across the street from the church. Or to go Mississippi and search for the three civil rights workers who came up missing. There is a lot of trauma.

I think all three of those men [James Mattis, Mike Pompeo and Rex Tillerson] that you just mentioned, depending on what deal was struck with Russia, depending on what terms the deal would have and what incremental steps we would have to take and measurements that we would have to take with potentially Russia in a deal, some of those positions could change, and some of President-elect Donald Trump's positions could change depending on what deal could be struck.

My parents told me in the very beginning as a young child when I raised the question about segregation and racial discrimination, they told me not to get in the way, not to get in trouble, not to make any noise.

Sensible people have got to work together.
