The police killings of unarmed African Americans has got to stop.

I think we should look to countries like Denmark, like Sweden and Norway, and learn from what they have accomplished for their working people.

In Germany, college tuition is free. In America, college tuition is increasingly unaffordable. In a highly competitive global economy, which country do you think will have the best educated work force and a competitive advantage? We must make tuition free in public colleges and universities and substantially reduce interest rates on student loans.

Here's something that I believe we have to do as we put together an international coalition, and that is we have to understand that the Muslim nations in the region - Saudi Arabia, Iran, Turkey, Jordan - all of these nations, they're going to have to get their hands dirty, their boots on the ground. They are going to have to take on ISIS.

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.

The point is change can come about, but it only comes about when millions of people are actively involved in political struggle, the billionaires may have the money, but we have the people.

I want to know in this day and age, whether it is possible for any candidate who is not a billionaire or who is not beholden to the billionaire class, to be able to run successful campaigns.
