I do believe that if millions of people do stand up and fight back, we can stop Donald Trump from doing some really awful things.

I think, with Trump, the major point is this guy has business enterprises all over the world. And you're looking just at immense, immense conflict of interest.

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.

The Republicans are many things, but they're not dumb.

I think my experience at the University of Chicago, working in the civil rights movement, working in the peace movement, working with community organizations, did a lot to influence the politics that I have.

At a time when the average student is graduating from a four-year college $27,000 in debt, when hundreds of thousands of capable young people no longer see college as an option because of high costs and when the U.S. is falling further and further behind our economic competitors in terms of the percentage of young people graduating from college, no agreement should be passed which, over a period of years, makes a bad situation worse and will make college even less affordable than it is today.

It would, I think, be hard for anyone to make the case that the United States is a just society or anything close to a just society. In America today, there is massive injustice in terms of income and wealth inequality. Injustice is rampant.
