As president of the United States, I don't bluff.

One of the things I've learned about being president is that we'll work on issues for long periods of time, sometimes in obscurity.

What I said to Donald Trump was that what may work in generating enthusiasm or passion during elections may be different than what will work in terms of unifying the country and gaining the trust even of those who didn't support him.

Not much happens in Russian Federation without Vladimir Putin.

As president, I decided that a strong, confident America could advance our national security by engaging directly with the Iranian government. We've seen the results.

That is the story of our history - whether it's the pursuit of prosperity for our people or the struggle for equality for all of our citizens, our commitment to stand up for our values abroad, and our sacrifices to make the world a safer place. Let us remember that we can do these things not just because of wealth or power, but because of who we are. One nation under God, indivisible, with liberty and justice for all.

It's the idea held by generations of citizens who believed that America is a constant work in progress; who believed that loving this country requires more than singing its praises or avoiding uncomfortable truths. It requires the occasional disruption, the willingness to speak out for what's right, and shake up the status quo.
