Senate Judiciary Committee Chairman, Arlen Specter, asks FBI to turn over all information about Mohammed Atta investigation by Able Danger.
Two military officers, Lt. Col. Anthony Shaffer and Capt. Scott Philpott, contend that a unit code-named ``Able Danger'' used data mining - searching large amounts of data for patterns - to identify Atta in 2000. Shaffer has said three other Sept. 11 hijackers were also identified.
In a letter to FBI director Robert Mueller, Sen. Arlen Specter, R-Pa., asked the agency for ``all information and documents it has'' on Able Danger, Shaffer, Philpott and any other people linked to the operation. The letter, dated Wednesday and distributed Thursday to reporters, also seeks a meeting between Specter's staff and FBI agent Xanthig Mangum.
