My family, frankly, they weren't folks who went to church every week. My mother was one of the most spiritual people I knew but she didn't raise me in the church, so I came to my Christian faith later in life and it was because the precepts of Jesus Christ spoke to me in terms of the kind of life that I would want to lead.

It's easier to make negative attacks and simplistic slogans [in social media] than it is to communicate complex policies.

If you're willing to put in the work, the idea is that you should be able to raise a family and own a home, not go bankrupt because you got sick, 'cause you've got some health insurance that helps you deal with those difficult times; that you can send your kids to college; that you can put some money away for retirement. That's all most people want. Folks don't have unrealistic ambitions. They do believe that if they work hard, they should be able to achieve that small measure of an American dream.

By 2025 we expect new spacecraft designed for long journeys to allow us to begin the first ever crewed missions beyond the Moon into deep space.

And a landing on Mars will follow and I expect to be around in see it.

I am absolutely certain that generations from now, we will be able to look back and tell our children that this was the moment when we began to provide care for the sick and good jobs to the jobless; this was the moment when the rise of the oceans began to slow and our planet began to heal; this was the moment when we ended a war and secured our nation and restored our image as the last, best hope on earth. This was the moment - this was the time - when we came together to remake this great nation so that it may always reflect our very best selves and our highest ideals.

I am encouraged by the president-elect's [Donald Trump] insistence that NATO is a commitment that does not change. And his full commitment to NATO as the foundation for our international security I think is very important.
