We are, however, producing a lot of natural gas, which serves as a bridge to more renewable fuels. And I think that's an important transition.

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.

I believe that, we're better when we're moving forward. We're stronger together, so that's what I'm going to be doing.

Children today will grow up taking for granted that an African-American or a woman can, yes, become the president of the United States.

When I was in the Senate, I had eight great years working with the community on major issues, trying to deal with problems that people brought to my attention. That's certainly what I intend to do as president. I think that is what President Obama has done.

Nobody should want to wake up on November 9th and wonder whether there was more you could have done.

The bottom line on nuclear weapons is that when the president gives the order, it must be followed. There's about four minutes between the order being given and the people responsible for launching nuclear weapons to do so. And that's why 10 people who have had that awesome responsibility have come out and, in an unprecedented way, said they would not trust Donald Trump with the nuclear codes or to have his finger on the nuclear button.
