We [with Donald Trump] just have a different view about what's best for growing the economy, how we make investments that will actually produce jobs and rising incomes.

We know that Donald Trump has shown a very troubling willingness to back up [Vladimir] Putin, to support Putin, whether it's saying that NATO wouldn't come to the rescue of allies if they were invaded, talking about removing sanctions from Russian officials after they were imposed by the United States and Europe together, because of Russia's aggressiveness in Crimea and Ukraine, his praise for Putin which is I think quite remarkable.

I think that trade is an important issue. Of course, we are 5 percent of the world's population; we have to trade with the other 95 percent. And we need to have smart, fair trade deals.

I agree with the secretary [Hillary Clinton] that I think what has to happen - and let me just mention what King Abdullah of Jordan said. I think he hit the nail on the head.

In America, we've been around for 240 years. We've had free and fair elections. We've accepted the outcomes when we may not have liked them. And that is what must be expected of anyone standing on a debate stage during a general election.

We came out of the White House not only dead broke, but in debt.

I don't think the police, even if we train them, can be, you know, as good as psychologists and psychiatrists and others knowing what is happening to somebody. So we've got to have a more coherent, comprehensive approach.
