Dragged through the mud

It was interesting to see George Bush praise Alberto Gonzales and hit out at his critics. I was amused that Bush had to hesitate, look at his notes and turn the page before he could decide what Gonzales' "good name" had been drug through. (He finally got out the word "mud." Watch the speech here.)

But partisan politics aside, who drug Gonzales' name through the mud?

On whose behalf did he advise the use of torture?
On whose behalf did he visit the hospital seeking authority form a sick man to indulge in illegal wiretaps?
On whose behalf did he fire US attorneys?
On whose behalf did he keep repeating, "I don't recall"?
On whose behalf did he speak untruthfully to congress?

These are the acts that plunged him into the mud. The one for whom he did them is the one who drug him into the mud.

George, why did you muddy your friend's reputation?
