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.

Donald Trump always puts himself first. He built a business career, in the words of one of his own campaign staffers, "off the backs of the little guy." And as a candidate, he started his campaign with a speech where he called Mexicans rapists and criminals, and he has pursued the discredited and really outrageous lie that President Obama wasn't born in the United States. 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 have lived according to rules that I embrace, but I don't feel like my job is to force others to embrace the rules that I embrace for myself.

I can be president of the United States, and if I can do that, I can do anything.

There are a series of connections between Donald Trump and his closest advisers and Russia that at least raise significant questions. Some of those questions could be answered if Donald Trump was willing to release his tax returns, but he's unwilling to do that.

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.

If somebody comes before me and I think that they will do a good job in fulfilling the mission - even if I might not have nominated them - if I think they're gonna do a good job, I vote for 'em.
