George W. Bush: “And there's no better place to come to see that happening than right here.”

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

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

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