Many documents produced by the U.S. government are confidential and not released to the public for legitimate reasons of national security. Others, however, are kept secret for more questionable reasons. The fact that presidents and other government officials have the power to deem materials classified provides them with an opportunity to use national security as an excuse to suppress documents and reports that would reveal embarrassing or illegal activities.
I’ve been collecting the stories of unreleased documents for several years. Now I have chosen 11 examples that were created—and buried—by both Democratic and Republican administrations and which cover assassinations, spying, torture, 50-year-old historical events, presidential directives with classified titles and…trade negotiations.
