George W. Bush: “I know he will work closely with me to build upon my administration's initiatives to make our air and water cleaner.”

Is it in our interest that 25 million people who would have died now live? I think it is. On behalf of a grateful nation, thank you for your hard work and God bless you.

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

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.
