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

If you want to run for the United States Senate, you hire a consultant who will do polling for you, who will tell you the kinds of television ads you should run, who will tell you that most of the money you raise has got to go into TV. Raising money, and then putting that money into the hands of consultants, who then put on TV ads - that's more or less what campaigns are about. We've got to change that.

If Mr. Trump wants to work with us to make sure that trade works for the American worker, not just CEOs of corporate America, you have got a partner, partner.

For many, the American Dream has become a nightmare.

I believe what Martin Luther King Jr. believed. You remember what the title of the March on Washington was? "Jobs and Freedom." What King understood is that you have to deal with the economic issues as well as the political issues and the civil rights issues.

You asked Marco Rubio if it was too little too late. I think there's a little bit of too much too late, which is, he is just getting down in the muck with Donald Trump. And when you get down in the muck, you get up with muck on you.

Giving up is not an option if we want to prevent irreparable harm to our planet.
