In addition to briefings about Able Danger with the Joint Chiefs of Staff (see Early 2001) and other military leaders (see March 2001), Lt. Col. Anthony Shaffer claims that there are other briefings about the project in the same early 2001 time frame. In one briefing, Shaffer says CIA Director George Tenet approves “our conduct of this special project—I did specifically mention the Able Danger effort to him regarding the use of its methodology to separate out US Person issues.” Shaffer also claims that the National Security Counsel (NSC) is briefed twice on Able Danger around this time. He says, “I cannot recall the specific dates of, or individuals present at, the briefing.” [US Congress, 2/15/2006 ]
