According to CBS News: "The admission came Thursday in response to a lawsuit filed by the ACLU, which sued in April after the Bureau of Prisons denied having any record of involvement with the detention site." In the November filing, the Bureau of Prisons acknowledged that two officials had visited the prison in 2002, but said that they had not technically lied when they denied having any record of the visit, because the CIA had instructed the BOP not to keep any record of the visit to be maintained.
