The United States Central Intelligence Agency has successfully defended itself against a lawsuit that sought the release of a secret document detailing the failed Bay of Pigs Invasion. On April 17, 1961, a brigade of 1,300 CIA-funded and -trained anticommunist Cubans mounted a surprise assault on the Caribbean island.
