A research group is demanding that the CIA declassify its five-volume, official history of the Bay of Pigs invasion of Cuba.
The National Security Archive filed a lawsuit Thursday in federal court in Washington, D.C., just in time for the 50th anniversary of the failed attack.
CIA Historian Jack Pfeiffer took nine years to compile the report. One volume of the report that was declassified sheds light on the role of then-Vice President Richard Nixon in the Bay of Pigs. The Archive filed a Freedom of Information Act request for the rest of the history in 2005 and says the CIA has wrongfully withheld it.
The head of the Archive's Cuba project, Peter Kornbluh, says 50 years is long enough for the rest of the history to be made public.
