[Donald Trump] said some very ill-considered, dangerous thing, and it's around the world in a nanosecond.

I plead - that it's very difficult when you deal with - ISIS and organizations like that whose - whose behavior is so barbaric and so vicious - that it doesn't seem to have any purpose other than lust for killing and power. And that's very difficult to put ourselves in other shoes.

In fact, Donald [Trump] was one of the people who rooted for the housing crisis.

I meet people who can't get healthcare for their families, people who are just distressed over what is happening in our country. So when somebody asks me, "How do you get up?" it really triggered in me the feeling that that's what I want us all to think about each other. How do we get up? How do we pull on our shoes, go out and deal with the problems America faces. That's what I intend to do as president.

That is what I want to make clear today. A man with a long history of racial discrimination, who traffics in dark conspiracy theories drawn from the pages of supermarket tabloids and the far, dark reaches of the Internet, should never run our government or command our military.

I believe in affordable college, but I don't believe in free college, because every expert that I have talked to says, look, how will you ever control the costs.

Climate change is such a consequential crisis to everybody in the world.
