You just have to sort of figure out how to - getting back to that word, "balance" - how to balance the public and the private efforts that are necessary to be successful, politically, and that's not just a comment about today. That, I think, has probably been true for all of our history.

The present system is unsustainable. The only question is whether we will master the change or it will master us.

If you look at what the factors were going into the decision, of course there are competing interests and values. And one of our values is we bring everybody home off the battlefield the best we can. It doesn't matter how they ended up in a prisoner of war situation... It does not matter.

I want to be the president for all Americans, regardless of your political beliefs, where you come from, what you look like, your religion.

I'm not concerned about what [Donald Trump] says about me. That doesn't matter to me. I'm going to stand up for immigrants. I'm going to stand up for American Muslims who are working hard in this country that they love and consider their own. I'm going to stand up for other women. I'm going to stand up for the right to choose.

As president, I'll set bold goals to combat climate change: generate enough renewable energy to power every home in America within 10 years and slash carbon pollution at home and around the world.

We should demand that Donald release all of his tax returns so that people can see what are the entanglements and the financial relationships that he has with the Russians and other foreign powers.
