S. Res. 60, Resolution to establish a select committee, February 7, 1973
The Senate unanimously passed a resolution establishing a select committee to study any illegal, improper, or unethical activities associated with the 1972 presidential election. The resolution itself was used as evidence in the 1974 District Court trial of Attorney General John Mitchell and others for their roles in the Watergate break-in and its cover-up.

The Watergate Break-in
On June 17, 1972, police arrested burglars in the Democratic National Committee headquarters at the Watergate complex in Washington, D.C. Evidence linked the break-in to President Richard Nixon’s re-election campaign. In February 1973 the Senate established a select committee chaired by Senator Sam Ervin of North Carolina to investigate the 1972 presidential election. The Senate investigation revealed the existence of audiotapes, the content of which proved incriminating to President Nixon, and ultimately led to his resignation. Nationally televised, the Watergate Committee hearings boosted public confidence in Congress.
This committee can serve another quite important function that neither a grand jury investigation nor a jury proceeding is equipped to serve, and that is to develop the facts in full view of all the people of America.
