The White House Plumbers, sometimes simply called the Plumbers, the Room 16 Project, or more officially, the White House Special Investigations Unit, was a covert White House Special Investigations Unit, established within a week after the publication of the Pentagon Papers in June 1971, during the presidency of Richard Nixon. Its task was to stop and/or respond to the leaking of classified information, such as the Pentagon Papers, to the news media. The work of the unit "tapered off" after the bungled "Ellsberg break-in" but some of its former operatives branched into illegal activities while still employed at the White House together with managers of the Committee to Re-elect the President, including the Watergate break-in and the ensuing Watergate scandal.[1] The group has been described as Nixon's "fixers".[2]
