The White House is such an extraordinary, simple, beautiful place. It's an extraordinary piece of our history, because it is the one thing that binds our country together. We don't have a king obviously, but we have this president, and the fact that almost all of them have lived in the same place, and so much history took place in those rooms. You can't help but feel awe-inspired by being there.
