Alec Station, the CIA’s bin Laden unit, discovers that al-Qaeda has established a communications hub and operations center in Sana’a, Yemen, and that there are frequent calls between it and Osama bin Laden in Afghanistan (see May 1996 and November 1996-Late August 1998). [Antiwar, 10/22/2008; PBS, 2/3/2009] According to Alec Station chief Michael Scheuer, the CIA learns of this “communications conduit” through a CIA officer detailed to the NSA and stationed overseas. According to Scheuer, the NSA “refuse[s] to exploit the conduit and threaten[s] legal action against the agency officer who advised of its existence.” Despite the threat, the officer continues to supply the information. Scheuer asks senior CIA officials to intervene with the NSA, but this only leads to “a desultory interagency discussion without resolution.” [Atlantic Monthly, 12/2004] Author James Bamford will say: “Scheuer knew how important the house [the operations center in Yemen] was, he knew NSA was eavesdropping on the house. He went to NSA, went to the head of operations for NSA,… Barbara McNamara, and asked for transcripts of the conversations coming into and going out of the house. And the best the NSA would do would be to give them brief summaries every… once a week or something like that, you know, just a report, not the actual transcripts or anything. And so he got very frustrated, he went back there and they still refused.” [Antiwar, 10/22/2008] Because of the lack of information, the CIA will actually build its own listening post to get some of the information the NSA is concealing from it (see After December 1996).
