There's no greater challenge and there is no greater honor than to be in public service.

I grew up in a very loving middle class family. My parents were educators. I'm not even the first PhD in my family. They tried to shield me, just as other parents in my neighborhood tried to shield their children. But you knew there was a reason that you couldn't go to that theme park or to a movie theater or to a hamburger stand. They couldn't shield you completely. What they did though was they never let it be an excuse for not achieving, and they always said racism is somebody else's problem, not yours. They tried in that way not to make us bitter about Birmingham.

Well, there's been plenty of ultimatums, and one thing that we better be very clear is that we can't continue to have the kind of defiance of the United Nations, the defiance of the international community that we've had.

Education is transformational. It changes lives. That is why people work so hard to become educated and why education has always been the key to the American Dream, the force that erases arbitrary divisions of race and class and culture and unlocks every person's God-given potential.

We need to fight protectionism with everything that we have because when there's a level playing field and when you have open markets and when free trade is flourishing, American workers, American farmers, Americans are going to benefit.

You cannot be on one hand dedicated to peace and on the other dedicated to violence. Those two things are irreconcilable.

The U.S. has since the end of World War II had an answer - we stand for free peoples and free markets, we are willing to support and defend them - we will sustain a balance of power that favors freedom.
