I don't believe people should to be able to own guns.

Over the last 15 months, we've traveled to every corner of the United States. I've now been in 57 states? I think one left to go.

I can say across Europe that many principles that have been taken for granted here around free speech, and around civil liberties and an independent judiciary, and fighting corruption, those are principles that, you know, not perfectly but generally, we have tried to apply not just in our own country but also with respect to our foreign policy.

We have a historic opportunity to prevent the spread of nuclear weapons in Iran, and to do so peacefully, with the international community firmly behind us. We should seize that chance.

This union may never be perfect, but generation after generation has shown that it can always be perfected.

Honestly this is not going to change unless the people who want to prevent these kinds of mass shootings from taking place feel at least as passionate, at least as mobilized and well-funded as the NRA and the gun manufacturers are because the politics in Congress are such where even members of Congress who know better are fearful if they vote their conscience and support common sense measures like background checks, they're worried they're going to lose.

Historically - when you look at how America has evolved, typically we make progress on race relations in fits and starts. We make some progress, and then there's maybe some slippage.
