Incident
United States government seeks an injunction to stop The New York Times publishing the Pentagon Papers

After The New York Times began publishing a leaked secret history of the Vietnam War, the Nixon administration obtained a court order stopping further publication, the first such order against a major American newspaper. The Supreme Court lifted it two weeks later, ruling the government had not justified blocking publication in advance.1
What happened
Military analyst Daniel Ellsberg copied a classified Defense Department history of United States involvement in Vietnam, later known as the Pentagon Papers, and gave it to The New York Times, which began publishing excerpts on June 13, 1971. The Department of Justice obtained a temporary restraining order from a federal court on June 15, 1971, the first time the United States government had gone to court to stop a major newspaper from publishing a specific story, arguing publication would harm national security. When The Washington Post also began publishing excerpts, the government sought an injunction against it too. The Supreme Court of the United States, the country's highest court, heard the consolidated case on an emergency basis and ruled 6 to 3 on June 30, 1971, in New York Times Co. v. United States, that the government had not met the heavy burden required to justify stopping publication in advance, and both papers resumed publishing.231
What reason was given
Stated justificationGovernment lawyers argued that publishing the classified history would cause grave and irreparable harm to United States national security and ongoing diplomatic and military efforts in Vietnam.3
What changed for reporting
The New York Times and The Washington Post were barred by court order from publishing further excerpts of the Pentagon Papers for roughly two weeks until the Supreme Court lifted the injunction.231
