On November 21, 2016, CBS News reported that an inspection of the Salt Pit, from officials from the United States Bureau of Prisons (BOP), had been confirmed through Freedom of Information Act (FOIA) lawsuits. The Bureau of Prison inspection first became public knowledge when the United States Senate Intelligence Committee published its 600-page unclassified summary of its (then-classified) 6,700 page report on the CIA's use of torture. The Bureau of Prison denied sending inspectors. The American Civil Liberties Union then filed FOIA requests for information about the inspections. When the Bureau of Prisons declined to honor the requests, the ACLU took the matter to court.
