I insist on the dignity and God- given potential and work of every child, regardless of race or gender or sexual orientation or what zip code they were born in.

Iran's Supreme Court has issued a fatwa against the development of nuclear weapons. President [Hassan] Rouhani has indicated Iran will never develop nuclear weapons. I've made clear that we respect the right of the Iranian people to access peaceful nuclear energy in the context of Iran meeting its obligations.

I don`t know if Donald Trump`s ever been to an actual polling place, but, you know, he doesn`t even worry if what he says is true. This is just about him worried that he`s losing.

We need to steer clear of this poverty of ambition, where people want to drive fancy cars and wear nice clothes and live in nice apartments but don't want to work hard to accomplish these things. Everyone should try to realize their full potential.

another tradition to politics, a tradition (of politics) that stretched from the days of the country’s founding to the glory of the civil rights movement, a tradition based on the simple idea that we have a stake in one another, and that what binds us together is greater than what drives us apart, and that if enough people believe in the truth of that proposition and act on it, then we might not solve every problem, but we can get something meaningful done.

Making your mark on the world is hard. If it were easy, everybody would do it. But it's not. It takes patience, it takes commitment, and it comes with plenty of failure along the way.

In the campaign back in 2007, 2008, people would say, "Oh, he's being naïve. He thinks that there's no red states and blue states. And wait 'til he gets here."

I did not expect, particularly in the midst of crisis, just how severe that partisanship would be.
