Rudy Giuliani hints that President Bush might want to turn to Michael Chertoff, a man Giuliani himself once hired, when picking a new attorney general.
Alberto Gonzales has been under fire for months and announced today that he was leaving office next month.
Giuliani is in Detroit to raise money for his presidential campaign and watch his New York Yankees play the Tigers.
He says it's critical that Bush pick a great lawyer who has the confidence of both major parties.
Giuliani declined to name his own favorites but mentioned Chertoff, who worked for him when Giuliani was the top federal prosecutor in New York.
Chertoff helped send top mobsters to prison.
