He's either lying or stupid with this statement (...or both).
Chertoff was Sleazy Al D’amato’s butt-boy during the Senate Whitewater (Whitewash) hearings that D’Amato chaired wth Chertoff as Chief Investigator. He caved when D’Amato SOLD OUT TO THE CLINTONS to save his own ass from indictment on issues dating bank to his sleazy days as a Long Island, NY Town Supervisor.
Chertoff = Comey = D’Amato = SELLOUT
