Pentagon Papers (1971)
The Nixon administration tried to stop the Times and Washington Post from publishing a secret history of the Vietnam War leaked by analyst Daniel Ellsberg. The Supreme Court ruled 6-3 that the government could not block publication.
The papers kept publishing and Ellsberg was charged, though his case later collapsed over government misconduct.
The ruling set a high bar against prior restraint and became the anchor case for U.S. press freedom.
It marks the constitutional floor this story sits above. The 2026 effort targets sources and reporters after the fact, not publication itself, the line the 1971 case drew.
