George W. Bush: “We have an obligation and a duty to remain strong, remain firm, and to bring these people to justice.”

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

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

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.
