Few challenges facing America and the world are more urgent than combating climate change. The science is beyond dispute and the facts are clear.

The United States does not have a monopoly on crazy people. It's not the only country that has psychosis. And yet we kill each other in these mass shootings at rates that are exponentially higher than anyone else. Well, what's the difference? The difference is that these guys can stack up a bunch of ammunition in their houses, and that's sort of par for the course.

I think I did in the sense that there's a whole generation coming up behind us that was engaged, inspired, worked for change during the course of my presidency, saw what was possible. And that generation, it's coming.

Theoretically, you can make, obviously, a powerful argument that centuries of slavery, Jim Crow, discrimination are the primary cause for all those gaps. That those were wrongs done to the black community as a whole, and black families specifically, and that in order to close that gap, a society has a moral obligation to make a large, aggressive investment, even if it's not in the form of individual reparations checks, but in the form of a Marshall Plan, in order to close those gaps. It is easy to make that theoretical argument.

On every front there are clear answers out there that can make this country stronger, but we're going to break through the fear and the frustration people are feeling. Our job is to make sure that even as we make progress, that we are also giving people a sense of hope and vision for the future.

What I want all of you to know is that we are going to bring those who killed our fellow Americans to justice.

So long as I'm Commander-in-Chief, we will sustain the strongest military the world has ever known. When you take off the uniform, we will serve you as well as you've served us - because no one who fights for this country should have to fight for a job, or a roof over their head, or the care that they need when they come home.
