George W. Bush: “I encourage all Americans to commemorate this milestone by honoring the courage of those who came before us.”

We are heartbroken by the loss of life and the agony so many are feeling.

I'm really happy to be back in this great state.

Violence and vitriol must be purged from the public square. Members of other political parties are not our enemies; they are our fellow citizens.
