I recently found an interesting 9/11 Commission document about the NSA in the National Archives. The handwritten note from one of the commission’s staffers, Gordon Lederman, shows that one of his acquaintances had lunch with NSA Director Michael Hayden on May 7, 2003. Before the lunch, the acquaintance called Lederman and asked him whether he had any questions he wanted put to Hayden. According to the note, Lederman’s reply was, “I suggested that [the acquaintance] ask what the 9/11 Comm could do in its investigation that would be most useful to DirNSA [Hayden].”
