I believe that climate change is the great global crisis that we face, environmental crisis. I believe that if you're serious about climate change, you don't encourage the excavation and transportation of very dirty oil.

I'm not going to tell you I know George W. Bush intimately. I'm not going to tell you we're best friends. I'll tell you I met him on a number of occasions. You know what? George W. Bush is a very nice guy. Very funny guy. His wife is a very nice woman; I thought she was a great first lady. George [W.] Bush was the worst president in the history of the United States of America... The issue is not Bernie Sanders. The issue is the Koch brothers. The issue is who owns America.

[Hillary] Clinton is too much into regime change and a little bit too aggressive without knowing what the unintended consequences might be. Yes, we could get rid of Assad tomorrow, but that would create another political vacuum that would benefit ISIS.

We are living in the richest country in the history of the world, yet we have the highest rate of childhood poverty of almost any major country and millions of people are struggling to put food on the table. It is my absolute conviction that everyone in this country deserves a minimum standard of living and we've got to go forward in the fight to make that happen.

The American people are sick and tired of hearing about your [Hillary Clinton] damn e-mails!

How do we say, why do you keep voting for people who are giving more tax breaks to billionaires, who are going to send your jobs abroad, not going to let you form a union, not going to allow your kids to go to college? Why do you keep voting for these guys?
