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.

We need to work on drug costs, and there's things we can work on on drug costs, especially Medicare Part D, to bring drug costs down.

Did Donald Trump apologize for taking after somebody in a Twitter war and making fun of her weight? Did he apologize for saying African-Americans are living in Hell? Did he apologize for saying President Obama was not even a citizen of the United States? You will look in vain to see Donald Trump ever taking responsibility for anybody and apologizing.

People shouldn't be afraid to bring up issues of bias in law enforcement.

America is a nation of immigrants. We have to have a functioning immigration system.

It is so painful to suggest that we go back to think about these days where an African-American could not be a citizen of the United States.

I am deeply worried about Donald Trump on matters of national security. He doesn't know anything himself about it, and he has appointed a national security adviser, Mike Flynn, who is a pro-Russia conspiracy theorist, and he's just put Steve Bannon, a guy with connections to white supremacy and antisemitism, onto the National Security Council.
