The Washington Post reveals that FBI agents have questioned nearly all 37 senators and congresspeople making up the 9/1 Congressional Inquiry about 9/11-related information leaks. In particular, in June 2002 the media reported that the day before 9/11 the NSA intercepted the messages “The match is about to begin” and “Tomorrow is zero hour”(see September 10, 2001). The FBI has asked the members to submit to lie detector tests but most have refused. Congresspeople express “grave concern” for this historically unprecedented move. A law professor states: “Now the FBI can open dossiers on every member and staffer and develop full information on them. It creates a great chilling effect on those who would be critical of the FBI.” [Washington Post, 8/2/2002] Senator John McCain (R-AZ) suggests that “the constitutional separation of powers is being violated in spirit if not in the letter. ‘What you have here is an organization compiling dossiers on people who are investigating the same organization. The administration bitterly complains about some leaks out of a committee, but meanwhile leaks abound about secret war plans for fighting a war against Saddam Hussein. What’s that about? There’s a bit of a contradiction here, if not a double standard.’” [Washington Post, 8/3/2002] Later the search for the source of the leak intensifies to unprecedented levels as the FBI asks 17 senators to turn over phone records, appointment calendars, and schedules that would reveal their possible contact with reporters. [Washington Post, 8/24/2002] Most, if not all, turn over the records, even as some complain that the request breaches the separation of powers between the executive and legislative branches. One senator says the FBI is “trying to put a damper on our activities and I think they will be successful.” [Associated Press, 8/29/2002] In January 2004, it will be reported that the probe is focusing on Sen. Richard Shelby (R-AL). He will not be charged with any crime relating to the leak. [Washington Post, 1/22/2004] In November 2005, the Senate Ethics Committee will announce it has dropped a probe of Shelby, citing insufficient evidence. [Reuters, 11/13/2005] Inquiry co-chair Sen. Bob Graham (D-FL) will write in a book in late 2004 that, at the time, he guessed “the leak was intended to sabotage [the inquiry’s] efforts. I am not by nature a conspiracy theorist, but the fact that we were hit with this disclosure at the moment we began to make things uncomfortable for the Bush administration has stuck with me. Over a year later, I asked [inquiry co-chair] Congressman [Porter] Goss (R-FL) whether he thought we had been set up. Nodding, he replied, ‘I often wonder that myself.’” [Graham and Nussbaum, 2004, pp. 140] Author Philip Shenon will observe that this tactic of intimidation worked, as “Members of the joint committee and their staffs were frightened into silence about the investigation.” [Shenon, 2008, pp. 55]
