Obviously in the next few months we have got to do everything that we can to make sure that Donald Trump, who in my view is the worst, least-prepared candidate for president in my lifetime. Number two, we've got to obviously elect Hillary Clinton.

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.

No president, not the smartest, best human being in the world can do it alone. You cannot take on this, the power that is in Washington, to billionaires and lobbyist, the military industrial complex, all of this money and power, you can`t do it. You need a mass movement of American who are looking in congress and we say directly.

We're going to stand with working people. We're going to take on the billionaire class. We're going the take on the drug companies and the insurance companies. We're going the take on Wall Street. That's where I think the future of the Democratic Party lies.

As an independent, my views, in fact, are a little bit different than many of my Democratic colleagues.

We are living at a time where a handful of people have wealth beyond comprehension - huge yachts, jet planes, tens of billions of dollars, more money than they could spend in a thousand lifetimes. But at the same time, millions of people are struggling to feed their families or put a roof over their heads or find the money to go to a doctor.

We have got to change the political culture in America. We need a political revolution. That means we are working on politics not just three weeks before an election but 365 days a year.
