Even in the civil rights movement, there were so many unbelievable women. They never, ever received the credit that they should have received. They did all of the, and I cannot say it, they did all of the dirty work. Hard work.

We all remember that [Donald] Trump was one of the leaders of the so-called birther movement trying to delegitimize the presidency of our first African-American president Barack Obama, which is an outrage.

Young people can understand, and must understand, that we had success, we had failures, but we never gave up. We never gave in. We never became bitter. We didn't hate. We continued to press on. And that's what we're saying: There are some ups, there are some downs, and when you're not down, you must have the capacity and the ability to get up and keep going.

If we must grind up human flesh and bones in the industrial machine that we call modern America, then, before God, I assert that those who consume the coal and you and I who benefit from that service, because we live in comfort, we owe protection to those men first and we owe security for their families if they die.

I think it is a must for young people and generations yet to come, to understand, to feel, to touch, to almost smell the drama of what happened a few short years ago [the civil rights movement of the 1950s and 1960s]. So maybe, just maybe, we will never ever repeat this unbelievable time in our history. We have to tell it all, and make it plain, and make it clear, so people will never ever forget the distance we have come, and the progress we have yet to make.

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.

If you see something that is not right, not fair, not just, you have a moral obligation to do something about it.
