Donald Trump has broken his first promise [to release taxes]. Second he stood on this stage last week and when Hillary said you haven't been paying taxes, he said, that makes me smart. So it's smart not to pay for our military. It's smart not to pay for veterans, it's smart not to pay for teachers and I guess all of us who do pay for those things I guess we're stupid.

The national security issues are a really good window into the character of the person that somebody wants to have as commander in chief.

Senate has to advise and consent. That doesn't mean you have to vote yes; you can vote no. It's not a rubber stamp. But what these guys are doing is, "Wait a minute, we don't have to vote yes or no, and maybe we can trick our voters into not holding us accountable for not voting yes or no."

Vladimir Putin is a dictator. He's not a leader. Anybody who thinks otherwise doesn't know Russian history and they don't know Vladimir Putin.

I think if you do term limits, you would really increase the power of lobbying.

Americans need to worry about whether Donald Trump will be watching out for America's bottom line or his own bottom line.

My sense is that economic anxiety means electoral volatility.
