A report issued by Mathew M Aid claims that  the CIA, the Defense Department, and the Department of Justice, amongst others—have reclassified some 9,500 documents, many of them dating from the Korean War and early Cold War eras.

Aid discovered the program in December when he noticed that dozens of documents that he had examined at NARA’s College Park, Maryland, facility years ago have been withdrawn, even some published previously in the State Department’s historical series, Foreign Relations of the United States.

“The stuff they pulled should never have been removed,” Aid said in the February 21 New York Times. “Some of it is mundane, and some of it is outright ridiculous.”
