On May 21, 2002, “Coleen Rowley, a lawyer in the [FBI’s] Minnesota office, sent a thirteen-page letter to [FBI Director Robert] Mueller expressing her ‘deep concern’ that the director and other FBI leaders were ‘shading/skewing’ the facts about the Bureau’s failures leading up to 9/11. Though she claimed ‘the term *cover-up* would be too strong a characterization,’ Rowley complained that a supervisory special agent at Headquarters had been ‘consistently, almost deliberately thwarting the Minneapolis FBI agents’ efforts’ to investigate [suspected terrorist] Zacarias Moussaoui in the weeks prior to the attacks. …Warning that Mueller himself had not been ‘completely honest’ about ‘the true reasons for the FBI’s pre-September failures,’ Rowley predicted that ‘until we come clean and deal with causes, the Department of Justice will continue to experience problems fighting terrorism and fighting crime in general.’ ”
