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.

We can't get to the $4 trillion in savings that we need by just cutting the 12 percent of the budget that pays for things like medical research and education funding and food inspectors and the weather service. And we can't just do it by making seniors pay more for Medicare.

Peace is not just the absence of war. True peace depends upon creating the opportunity that makes life worth living. And to do that, we must confront the common enemies of human beings: nuclear weapons and poverty; ignorance and disease.
