Pentagon Papers

The Pentagon Papers are a 47-volume study of the United States' involvement in the Vietnam War from 1945 to 1968, commissioned by Secretary of Defense Robert McNamara in June 1967. The study was initially kept secret and was later leaked to the public by Daniel Ellsberg, who was working on the study, and was first published in The New York Times in 1971. The Pentagon Papers revealed that the US had secretly enlarged the scope of its actions in the Vietnam War, and that Lyndon B. Johnson's administration had "systematically lied, not only to the public but also to Congress." The study was declassified and publicly released in June 2011.learn more on wikipedia
