Remember the hours after Sept. 11 when we came together as one...It was the worst day we have ever seen, but it brought out the best in all of us.

I promise just to serve two terms. Republicans do it differently. They just have the son repeat the father's whole first term.

The future belongs to freedom, not to fear.

It's one thing to be certain, but you can be certain and you can be wrong.

Think about this: terrorism, epidemics, poverty, the proliferation of weapons of mass destruction-all challenges that know no borders-the reality is that climate change ranks right up there with every single one of them.

This revolution began with young people in Syria demonstrating because they wanted a future. They wanted opportunity, education, and so forth. They went out and they did it. Thugs came out and beat them up. The parents got angry that the thugs beat the kids up, and they went out and demonstrated, and they were met with bullets. They were killed. That's how this began.

Those who try to stifle the vibrancy of our democracy and shield policies from scrutiny behind a false cloak of patriotism miss the real value of what our troops defend and how we best defend our troops. We will ask questions and we will defend our democracy.
