Barack Obama: “We must seek a definitive end to conflict, gross human rights abuses, and genocide in Darfur.”

Every president here today, as different as we are, has tried our best to uphold the values that John McCain and Mitt Romney believed in no less than I did.

The success of this experiment was never a given.

We don’t have any folks who grill here?

I hope this center will serve as an affirmation of just how special, how precious our democracy truly is.
