Who is going to refuse to serve if asked by the President of the United States. I did not like Bill Clinton but had he asked me to serve I would, no one turns down the president of the United States when he personally asks for thier service.
They likely pre-emptively asked Al Gonzales that he take their names off the list so that Bush wouldn't ask them.
Bill Clinton is not worthy of wiping my shoes. If he asked me I would tell him were to put it.
