In 1971, White House Chief of Staff H. R. Haldeman, domestic affairs assistant John Ehrlichman, counsel John Dean, and staffer Jack Caulfield developed Operation Sandwedge as a clandestine intelligence program for Richard Nixon’s 1972 reelection campaign. Caulfield’s September 1971, twelve-page proposal sought a budget of $500,000—about $3.97 million in 2025 dollars—for private investigators, electronic surveillance, and security operations. It contemplated illegal “black bag” activities against Democratic candidates, anti–Vietnam War activists, Republican rivals, journalists, and other perceived enemies, including scrutiny of tax records, finances, and sexual behavior. Caulfield had already arranged wiretaps involving Nixon’s brother Donald and journalist Joseph Kraft, according to the source.
Campaign lawyer Herb Kalmbach transferred $50,000 to Caulfield at the request of campaign director John N. Mitchell, while Haldeman pressed Mitchell for as much as $800,000 for surveillance and miscellaneous activities. In October 1971, control shifted to G. Gordon Liddy, who expanded the concept into Operation Gemstone, including infiltration, wiretapping, sabotage, and a proposed break-in at Democratic offices in the Watergate complex. Sandwedge funding was ultimately rejected, but the related Gemstone activities produced the Watergate burglaries and cover-up. Of 69 people tried in the broader scandal, 48 pleaded guilty; Haldeman, Ehrlichman, Mitchell, John Dean, and Jeb Magruder were convicted for concealment, while Liddy was convicted for the break-ins. Nixon resigned on August 8, 1974, the only U.S. president to do so.
