For Democrats to win, they're going to have to address the needs of working people. They're going to have to address the needs of the middle class. And that means standing up to Wall Street, standing up to the greed of corporate America. Even now and then, standing up to the media. And that means having a candidate who can excite working families, excite young people, bring them into the political process, create a large voter turnout.

I don't believe there's a red state in America where people believe you should cut Medicare, Social Security and veterans' benefits rather than doing away with corporate tax loopholes.

Our goal there, in my view, is to work and lean strongly on China to put as much pressure. China is one of the few major countries in the world that has significant support for North Korea, and I think we got to do everything we can to put pressure on China. I worry very much about an isolated, paranoid country with atomic bombs.

I think the way for [Marco] Rubio to say to [Donald] Trump supporters, hey, essentially he's conned you. He's a con man. That's what they do. You pour gold people.My goodness, that's not the way to bring them in.

I very strongly supported the agreement which makes certain that Iran does not get a nuclear weapon.

Demagogues like [Donald] Trump come along. He says I know what the cause is. Remember, later, the cause was that Mexicans who are coming to this country, well, they were criminals or rapists. Now it is Muslims.

What we have got to do immediately is to say that racism and xenophobia is totally unacceptable and we will stand with the 1 percent of our population who are Muslims, for undocumented people in this country. Absolutely, we will stand.
