One of the challenges over the last decade is America has done experiments in nation building in places like Iraq and Afghanistan and we've neglected, for example, developing our own economy, our own energy sectors, our own education system. And it's very hard for us to project leadership around the world when we're not doing what we need to do.

Over the last few years a lot of people have become aware of the inequities in the criminal justice system, right now, with our overall crime rate and incarceration rate both falling, we're at a moment when some good people in both parties, Republicans and Democrats and folks all across the country, are coming up with ideas to make the system work smarter and better.

We rise and fall as one people, one nation.

We have come from a time of the large-scale, planned, Al Qaeda-style attacks, to the encouragement of lone wolves: Fort Hood, Chattanooga. To the encouragement of people to act on their own.

Money is the original sin in politics and I am not sinless.

We need to spend a trillion dollars rebuilding our schools, our roads, our basic science and research here in the United States.

The shift to a cleaner energy economy wont happen overnight, and it will require tough choices along the way. But the debate is settled. Climate change is a fact.
