Senior CIA officials have for years intentionally deceived parts of the agency workforce by transmitting internal memos that contain false information. The practice is known by the term eyewash. Officials said there is no clear mechanism for labeling eyewash cables or distinguishing them from legitimate records being examined by the CIAs inspector general, turned over to Congress or declassified for historians. Senate investigators uncovered apparent cases of eyewashing as part of a multi-year probe of the CIAs interrogation program, according to officials who said that the Senate Intelligence Committee found glaring inconsistencies in CIA communications about classified operations, including drone strikes. Former CIA officials ... acknowledged that the internal mechanisms for managing eyewash cables were largely informal. Skeptics described the safeguards as inadequate. When you introduce falsehoods into the communications stream then you can destabilize the whole system of intelligence oversight and compliance with the law, said Steven Aftergood, a government secrecy expert at the Federation of American Scientists. It wasnt that long ago that we had a CIA executive director who was engaged in criminal activity - you dont want someone like him preparing eyewash cables, Aftergood said, referring to Kyle Dusty Foggo, the former No. 3 executive at the agency.
