Donald Trump believes that climate change is a hoax. Now, this is not just a stupid expression, but it is incredibly dangerous.

In fact, climate change is directly related to the growth of terrorism.

The future of the Democratic Party, the future of this country is involving young people in the political process, getting them to stand up for their rights, dealing with student debt, which I got to tell you is just crushing people all over this country, making public colleges and universities tuition free, those are the ideas we are bringing out, demanding the wealthy and large corporations start paying their fair share of taxes. This is what younger people, working class people want. That is the future of the Democratic Party.

We need a very progressive and strong agenda to bring people into the political process because I worry very much about the future of the American democracy where so many people are giving up.

I think - you know, I can't speak for 13 million people, but I think most of my supporters understand Trump has got to be defeated. We need to elect as many progressives as possible. And we need to continue the fight to create an agenda which works for working families and not just for wealthy campaign contributors.

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.

Of course their [Cuba's] economy is terrible, but they have Health Care and education.
