Let it be said to our children's children that when we were tested we refused to let this journey end, that we didn't turn our back nor did we falter; and with eyes fixed on the horizon and God's grace upon us, we carried forth that great gift of freedom and delivered it safely to future generations.

[Michelle Obama] used to say to our friends, "Barack's exactly the kind of guy I want to be president. I just wish he didn't want to do it when I was married to him."

I want to make sure America has got the best education system in the world. And we're retaining our workers for the jobs of tomorrow.

I found during the course of my political career on the national scene there's a point where the vanity burns away and you've had your fill of your name in the papers, or big adoring crowds, or the exercise of power. And for me that happened fairly quickly. And then you are really focused on: What am I going to get done with this strange privilege that's been granted to me? How do I make myself worthy of it?

What we've seen at least since 1979 is Iran making constant, calculated decisions that allow it to preserve the regime, to expand their influence where they can, to be opportunistic, to create what they view as hedges against potential Israeli attack in the form of Hezbollah and other proxies in the region.

If Iran cheats, the world will know it.

The only time I get frustrated with activist criticism is if I have recognized them, and invited them to work with me to figure out how we solve this problem that they're concerned about, and either they don't engage out of the sense of purity - "I'm not going to shake his hand" - or you're not sufficiently prepared so you don't even know what to ask for, or you're not being strategic as an activist and trying to figure out how the process has to work in order for you to get what you want.
