The Facts of New York Times v. United States:
The New York Times and Washington Post began publishing portions of the
"Pentagon Papers" (a secret Defense Department report of U.S. involvement in
Vietnam). The Pentagon Papers only pertained to events up to 1968.The Nixon
Administration argued that this information was useful to the enemy and might
prolong the war. Therefore the government sought an injunction against the
papers to prevent further publications.
