What I said to Donald Trump was that what may work in generating enthusiasm or passion during elections may be different than what will work in terms of unifying the country and gaining the trust even of those who didn't support him.

Never give up on your dreams.

Donald Trump is somebody who I think likes to mix it up and to have a vigorous debate.

We remember the specter of sectarian violence -- al Qaeda's attacks on mosques and pilgrims, militias that carried out campaigns of intimidation and campaigns of assassination. And in the face of ancient divisions, you stood firm to help those Iraqis who put their faith in the future.

I'm going to insist on making sure that we've got decent funding, that we've got enough teachers, that we've got computers in the classroom, but unless you turn off the television set and get over a certain anti-intellectualism that I think pervades some low-income communities, our children are not going to achieve.

The Internet and Twitter and all these things are very powerful, but it also means sometimes that instead of having a dialogue we just start calling folks - calling each other names. And that's true on the left or the right.

If we don't reform how healthcare is delivered in this country, then we are not going to be able to get a handle on that escalating healthcare costs.
