Barack Obama: “I say if Stephen Colbert wants to play soldier, it's time to cut that man's hair.”

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

We designed the center not to be some lifeless mausoleum.

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.

They're meant to remind us of who we can be, to remind us of what's possible, so we can forge ahead.
