June 19, 1972

June 19, 1972, was the date the Supreme Court declared illegal the Nixon administration’s use of electronic eavesdropping without court authorization against people suspected of domestic subversive activity. The ruling came just two days after the Watergate arrests, placing a sharp legal limit on surveillance powers the administration had claimed in the name of national security—and giving added weight to reporters’ emerging questions about how those powers had been used.

The Surveillance Policy and the Ruling

The administration’s policy, also known as the Mitchell Doctrine (national-security wiretapping policy), asserted unprecedented authority to conduct electronic surveillance. The Justice Department had used warrantless eavesdropping against people suspected of domestic subversive activity; critics argued that the label could be used for people who dissented strongly from the administration’s policies. The Supreme Court’s June 19 ruling made the legal status of that practice explicit: electronic surveillance without court authorization was illegal.

The ruling also marked the end of a period of surveillance later described as beginning in 1969. According to a subsequent account in Time magazine, FBI taps on the telephones of reporters and government and White House aides continued until June 19, 1972. The account said that J. Edgar Hoover had permitted the taps only after John Mitchell authorized each one in writing, and that the operation continued under acting FBI director L. Patrick Gray III.

From the Ruling to the Reporters’ Inquiry

The ruling did not settle whether reporters or government officials had been among those monitored. Working from a White House telephone directory, Bob Woodward and Carl Bernstein contacted people who had served under John Ehrlichman. A former and a current White House staff member independently described David Young, a former aide to Henry Kissinger and deputy on the White House Plumbers project, routing transcripts of wiretapped conversations to E. Howard Hunt and G. Gordon Liddy in 1971 and 1972. Both sources also suspected that reporters and possible leakers had been tapped.

Woodward’s resulting account reported that Hunt and Liddy had received information from national-security wiretaps routed through Young, who was also a Plumber. It set out those connections without claiming to establish whether the journalists themselves had been monitored. Asked about the report, White House spokesman Gerald Warren said that checking had found no basis for it, but would not give a flat denial. The distinction between a documented route for surveillance material and unanswered questions about its targets remained central to the reporting.

Later Account and Significance

Two weeks later, Time magazine published a detailed account of the administration’s campaign to trace news leaks by tapping reporters’ and government officials’ telephones. It reported that the FBI had tapped the phones of half a dozen reporters and twice as many White House and government aides for domestic-security reasons, and described Mitchell’s written authorization of individual taps. The account also said Hoover had threatened to reveal details of the program when the administration tried to force him to retire in 1971.

June 19 therefore serves as both a legal turning point and a chronological hinge in the account of the surveillance. The Court’s ruling closed the period in which the administration had claimed authority for warrantless domestic wiretapping; the later disclosures showed how long that surveillance had operated and how its records and transcripts entered the work of the Plumbers. The date did not itself answer who had been targeted or what officials knew, but it sharpened the legal and political stakes of finding out.
