The good news is that the Paris Agreement is not just a bilateral agreement between the United States and some other country. You have 200 countries who came together. It's an international agreement.

Democracy is hard work.

Michelle [Obama] never fully took to the scrutiny. I mean, she's thrived as a first lady, but it's not her preference.

For we have a choice in this country. We can accept a politics that breeds division, and conflict, and cynicism. We can tackle race only as spectacle - as we did in the OJ trial - or in the wake of tragedy, as we did in the aftermath of Katrina - or as fodder for the nightly news. We can play Reverend Wright's sermons on every channel, every day and talk about them from now until the election, and make the only question in this campaign whether or not the American people think that I somehow believe or sympathize with his most offensive words.

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.

I will never apologize for saying that the future of humanity and the future of the world is going to be defined by what we have in common as opposed to those things that separate us and ultimately lead us into conflict.

The sort of seeing cruelty and callousness of that sort from young people is heartbreaking.
