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

Midterm elections for first-term presidents are notoriously difficult.

Donald Trump must give the American public his tax returns to show that he's qualified to be president and he's breaking his promise.

I worry that a Trump presidency doesn't show the true face of America to the world, but I think that peaceful protest all around this country, it showed to the world who we really are.

I think we need to fight against Trumpism in the courts, we need to fight at the ballot box and online, and we need to do peaceful protesting. We need to use every lever at our disposal to make sure that the president doesn't hurt our country, our values, and our people.

If you want to have a society where people are respected and respect laws, you can't have somebody at the top who demeans every group that he talks about. And I just - again, I cannot believe that Governor Pence will defend the insult-driven campaign that Donald Trump has run.

I think if you run away from who you are, that you're a Democrat and you're proud to be a Democrat, it's foolish. And the reason it's foolish is you've got a lot to be proud of.
