Reverend Wright has been my friend and mentor for over 20 years.

It's important to know that the vast majority of people who were excited in 2008 are still really enthusiastic. We've got more volunteers now than ever, and they're engaged, they're motivated, they're not paying attention to the ups and downs of polls or Washington.

I do believe, separate and apart from any particular election or movement, that we are going to have to guard against a rise in a crude sort of nationalism or ethnic identity or tribalism that is built around an us and a them.

I actually believe that we need missile defense, because of Iran and North Korea and the potential for them to obtain or to launch nuclear weapons, but I also believe that, when we are only spending a few hundred million dollars on nuclear proliferation, then we're making a mistake.

I look forward to teaching the occasional class, 'cause I was a professor. And I had fun doing it.

In America, we want a peaceful planet. We want people to be able to enjoy their lives and know they're going to have a bright and prosperous future, not be at war. That's our purpose.

You bomb ISIL. You're not trying to bomb innocent people. And that requires intelligence and confidence in our military to be able to develop the kinds of targets that we need. We're already doing Special Forces, who are going to help us gather that intelligence and help advise and assist and train local forces so that they can go after ISIL in areas like Raqqah and Mosul.
