We saw more evidence that [Doanld Trump] is temperamentally unfit and totally unqualified to be commander-in-chief. He trash-talked American generals, saying they had been, quote, "reduced to rubble," that's how he talks about distinguished men and women who have spent their lives serving our country, sacrificing for us. That's how he would act as commander-in-chief.

Our country deserves no less, because all of the other issues we want to deal with depend upon us being secure and strong.

We want to lead by our values and out interests in ways that, regardless of the trajectory over the next decade, people will know the United States was on the side of democracy, on the side of the rule of law.

While Donald Trump was busy with his accountants trying to figure out how to keep living like a billionaire, and all the while he was using his political connections to collect hundreds of millions of dollars in government subsidies and extra tax breaks for his companies. In other words, Trump was taking from America with both hands, and leaving the rest of us with the bill.

I'm really looking forward to both meeting with Sen. [Bernie] Sanders as soon as our campaign teams find a time that works for both of us and talking with him about how we are going to defeat Donald Trump and then how the goals that he and I share can be achieved.

Part of diplomacy, the hard work of diplomacy is trying to extract whatever concessions you can get, and giving something the other side wants. Of course you've got to try to make peace with, and work with those who are your adversaries, but you don't just rush in, open the door, and say, "Here I am. Let's talk and make a deal."

You will not find that I ever changed a view or a vote because of any donation that I ever received.
