On 6/13/1971 The New York Times began publishing the "Pentagon Papers," a top-secret Defense Department study on the United States political and military involvement in Vietnam from 1945 through 1967. On the 40th anniversary, this Monday, June 13th, our government will mark the study declassified and release it to the public.
