If you`re a Republican politician and you`re seeing this guy [Donald Trump] saying crazy stuff and going up in the polls, what are you going to say, you`re going to say equally crazy or maybe a little less crazy stuff.

Not only did I vote against that war, I helped lead the opposition, and if you go to my website, berniesanders.com, you will see the statement that I made in 2002.

The focus, to my mind, is to make sure that Donald Trump does not become president of the United States. I think by temperament he is unqualified to be president. I think his views - you have a guy who's running for president who rejects science, doesn't even believe climate change is real, let alone wants to do something about it, wants to give hundreds of billions of dollars in tax breaks to the top two-tenths of one percent.

If you want to talk about somebody who's actually been tough on Russia, look at President Trump. He wants more fracking, more coal, more energy, a stronger military, a stronger defense. Those things aren't good for Russia.

Secretary [Hillary ] Clinton is absolutely right, there are people, Koch brothers among others, who have a group called Concerned Veterans of America, funded by the Koch brothers. The Koch brothers, by the way, want to destroy Social Security, Medicare, Medicaid, every governmental program passed since the 1930s. Yes, there are people out there who want to privatize it.

The Fed has got to become a more democratic institution that is responsive to the needs of the middle class, not just Wall Street CEOs.
