You have countries like India that have tried to help untouchables, with essentially affirmative-action programs, but it hasn't fundamentally changed the structure of their societies.

I've said consistently that I always reserve the right, in conjunction with a broader international effort, to prevent genocide or any wholesale slaughter than might happen inside of Iraq or anyplace else.

That's what building a body of work is all about. It's about the daily labor, the many individual acts, the choices large and small that add up over time, over a lifetime to a lasting legacy. It's about not being satisfied with the latest achievement, the latest gold star, because the one thing I know about a body of work is that it's never finished. It's cumulative. It deepens and expands with each day you give your best. You may have setbacks and you may have failures, but you're not done.

I still don't feel responsible for what Donald Trump says or does. But I do feel a responsibility as president of the United States to make sure that I facilitate a good transition and I present to him as well, as the American people my best thinking, my best ideas about how you move the country forward. To speak out with respect to areas where I think the Republican party's wrong, but to pledge to work with them on those things that I think will advance the causes of security and prosperity and justice and inclusiveness in America.

My job is not to represent Washington to you, but to represent you to Washington.
