For all the injustices in our past and our present, we have to believe that in the free exchange of ideas, justice will prevail over injustice, tolerance over intolerance and progress over reaction.

[Donald Trump] said, back in 2006, "Gee, I hope it does collapse, because then I can go in and buy some and make some money." Well, it did collapse.

The facts are - I did say I hoped it [Trans-Pacific Partnership] would be a good deal, but when it was negotiated which I was not responsible for, I concluded it wasn't. I wrote about that in my book.

The way Donald Trump talks about terrorism and his very insulting language towards Muslims is making him the recruiting sergeant for ISIS.

What difference, at this point, does it make?

We do not have to choose between a healthy environment and a healthy economy.

We'll get things done together. Democrats, Republicans, independents, we're going to make progress together when I'm president.
