George W. Bush: “We're already in a crisis.”

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

We know our words cannot help, but we believe the prayers of so many Americans will.

You've showed the great strength of America through your work—and that is your good heart.

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