It's true that America can't solve every problem, but I don't know of any major problem in the world that can be solved without us.

If I remembered when people said mean things about me, I would never speak to the media again.

I believe that when we have millions of hard-working immigrants contributing to our economy, it would be self-defeating and inhumane to try to kick them out. Comprehensive immigration reform will grow our economy and keep families together, and it's the right thing to do.

I'm going to continue to push for a no-fly zone and safe havens within Syria not only to help protect the Syrians and prevent the constant outflow of refugees, but to, frankly, gain some leverage on both the Syrian government and the Russians so that perhaps we can have the kind of serious negotiation necessary to bring the conflict to an end and go forward on a political track.

I have a number of proposals how to tackle this issue of self radicalization. I would set up a team exclusively dedicated to detecting and preventing lone wolf attacks.

I want to - on behalf of myself, and I think on behalf of a majority of the American people, say that, you know, our word is good.

I think people do want change, but we want to make sure that the change will actually help people. And that's why I reject the change agenda that Donald Trump has.
