On September 11th, 2001, in our time of grief, the American people came together. We offered our neighbors a hand and we offered the wounded our blood. We reaffirmed our ties to each other and our love of community and country. On that day, no matter where we came from, what God we prayed to, or what race or ethnicity we were, we were united as one American family.

ISIS is a virulent, nasty organization that has gained a foothold in ungoverned spaces effectively in Syria and parts of western Iraq. We have to take it seriously. They've shown in Paris what they can do in an organized fashion.

If you want a model for what is possible, if you want to see how to build a peaceful and prosperous and dynamic society, then look at Berlin and look at Germany.

Better may not be as good as the best, but better is surprisingly hard to obtain. And better is actually harder than worse.

I guarantee that there is no political influence in any investigation conducted by the Justice Department or the FBI, not just in this case, but in any case, full stop, period.

If you look at sort of how politics has divided itself here in this country, the big divide right now is between urban areas, which have become increasingly Democratic, and rural or exurban areas that feel as if they're being ignored.

One of the challenges of a democratic government is making sure that even in the midst of emergencies and passions, we make sure that rule of law and the basic precepts of justice and liberty prevail.
