We have got to mobilize people and rethink our commitment in terms of what our role is in the political process.

I believe, along with Pope Francis and almost all scientists, that climate change is threatening this planet in horrendous ways, and that we have to be aggressive in transforming our energy system away from fossil fuel and defeat the Keystone Pipeline.

In terms of Iran and in terms of Saudi Arabia, of course they hate each other. That's no great secret. But John Kerry, who is I think doing a very good job, has tried to at least get these people in the room together because both of them are being threatened by ISIS.

I am proud of the campaign that we ran. Obviously, I wish we could have done a little bit better.

On many, many issues, Hillary Clinton's views are progressive. In many areas, they are awesome. Where they're not progressive, we've got to push her, and the day after the election, I will mobilize millions of people to make sure that we make her the most progressive president that she can be.

I think, when the African-American community understands my record on criminal justice, my record on economics, the agenda we're bringing forth, raising the minimum wage to $15 an hour, dealing with the fact that we have more people in jail, shamefully, than any other country on Earth, that I am against the death penalty, Secretary Clinton is not, I think, as people become familiar with my ideas, we are going to do better and better.

I do believe that billionaires and multi-millionaires should be paying more in taxes.
