When I was in the Senate, I had a number of trade deals that came before me, and I held them all to the same test. Will they create jobs in America? Will they raise incomes in America? And are they good for our national security? Some of them I voted for.

It just seems to me that this is something that the American people deserve to see. And I have no reason to believe that [Donald Trump] is ever going to release his tax returns, because there's something he's hiding.

If you are too dangerous to get on a plane, you are too dangerous to buy a gun.

In fact, [Donald's Trump] cavalier attitude about nuclear weapons is so deeply troubling.

I do have investments, investments in new jobs, investments in education, skill training, and the opportunities for people to get ahead and stay ahead. That's the kind of approach that will work.

Never waste a good crisis.

At the end of the day, you know, love does not happen between two perfect people as much as we would wish.
