On June 17, 1972, operatives of Nixon's re-election committee were arrested in the DNC offices. They were paid with laundered campaign money, including the Ogarrio checks cashed through Mexico City. On the June 23, 1972 'smoking gun' tape, Nixon directs Haldeman to have the CIA tell the FBI to stop the investigation on 'national security' grounds. An 18½-minute gap sits on the June 20 tape. Nixon resigned on August 9, 1974. 69 people were charged, including two cabinet members; most pleaded guilty or were convicted.
