I think we have two conflicting traditions in this country. I think it's important for us to recognize that we've got a tradition of handgun ownership and gun ownership generally. And a lot of people - law-abiding citizens use if for hunting, for sportsmanship, and for protecting their families. We also have a violence on the streets that is the result of illegal handgun usage. And so I think there is nothing wrong with a community saying we are going to take those illegal handguns off the streets.

For the sake of our children and our future, we must do more to combat climate change. Now, it's true that no single event makes a trend. But the fact is the 12 hottest years on record have all come in the last 15. Heat waves, droughts, wildfires, floods-all are now more frequent and more intense. We can choose to believe that Superstorm Sandy, and the most severe drought in decades, and the worst wildfires some states have ever seen were all just a freak coincidence. Or we can choose to believe in the overwhelming judgment of science-and act before it's too late.

I don't want to make promises, not knowing what the situation's going to be three or four years out.

You have to have a strong team around you [being a president].

To this day, the United States is profoundly grateful for our friendship and alliance with Greece.

As I've said, there were patriots who supported this war, and patriots who opposed it. And all of us are united in appreciation for our servicemen and women, and our hopes for Iraqis' future.

I would not be running for President if I didn't believe with all my heart that this is what the vast majority of Americans want for this country. This union may never be perfect, but generation after generation has shown that it can always be perfected. And today, whenever I find myself feeling doubtful or cynical about this possibility, what gives me the most hope is the next generation - the young people whose attitudes and beliefs and openness to change have already made history in this election.
