I never regret anything... I just lie about it or change the story.

I know starting careers in troubled times is a challenge, but it is also a privilege. Because it's moments like these that force us to try harder, dig deeper and to discover gifts we never knew we had. To find the greatness that lies within each of us. So don't ever shy away from that endeavor. Don't stop adding to your body of work. I can promise that you will be the better for that continued effort as will be this nation that we all love.

If we have the kinds of confirmation that we need, we will once again work with the international community and the organization charged with monitoring compliance by the Syrian government, and we will reach out to patrons of Assad like Russia to put a stop to it.

My guiding principle as president has been to try to do the right thing even when it's not politically convenient.

We’re making new investments in the development of gasoline and diesel and jet fuel that’s actually made from a plant-like substance-algae... We could replace up to 17 percent of the oil we import for transportation with this fuel that we can grow right here in the United States.

Is this money well spent? This is taxpayer money, it is going to be adding to the deficit short term and if we can't justify it, then we're not going to spend tens or hundreds of billions of dollars, just to make somebody happy, if it's not good for the economy.

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.
