New York Times Begins Publishing the Pentagon Papers

Context

By the late 1960s, American public confidence in the Vietnam War had eroded amid mounting casualties and discrepancies between battlefield reports and administration statements. Successive presidents from Truman onward had framed U.S. engagement in Southeast Asia as essential to containing communism, yet the conflict expanded far beyond initial limited commitments. In 1967, Defense Secretary Robert McNamara commissioned a comprehensive internal study of American decision-making in Indochina dating back to the 1940s, assigning the task to a team of analysts within the Department of Defense.

What Happened

The resulting 47-volume report, completed in 1969, documented how four administrations had systematically understated the scale and prospects of U.S. involvement while pursuing policies that proved increasingly costly. Former Defense Department analyst Daniel Ellsberg, who had worked on the study and grown disillusioned, photocopied portions and attempted to share them with sympathetic senators in March 1971. When that effort stalled, he provided the materials to New York Times reporter Neil Sheehan. On June 13, the newspaper began publishing excerpts, revealing internal assessments that contradicted public optimism about the war's trajectory.

Aftermath

The Nixon administration immediately sought a court injunction to halt further publication, citing national security concerns. A federal judge issued a temporary restraining order after three days of excerpts appeared. The Times, joined by the Washington Post, appealed the case all the way to the Supreme Court. On June 30, 1971, the Court ruled 6-3 in New York Times Co. v. United States that the government had not met the heavy burden required to justify prior restraint, allowing publication to resume. The episode prompted the White House to form a Special Investigations Unit, later known as the Plumbers, tasked with plugging leaks.

Legacy

The Pentagon Papers deepened widespread skepticism toward government statements on foreign policy and reinforced constitutional protections for the press against prior restraint. The revelations contributed to the political environment that supported the withdrawal of U.S. forces from Vietnam and the passage of the War Powers Resolution in 1973, which sought to limit presidential authority to commit troops without congressional approval. Historians view the episode as a pivotal moment in the erosion of trust between the public and federal institutions during the Vietnam era.
