George W. Bush: “We're determined to build a future of security.”

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.

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

History will remember him as among the finest public servants of his generation – a patriot who brought integrity, high intelligence, and seriousness of purpose to every position.
