A bipartisan Senate investigation of activities by the Federal Bureau of Investigation (FBI) and the Central Intelligence Agency (CIA) is launched by a special congressional committee headed by Senator Frank Church of Idaho. On November 20, the committee released its report, charging both U.S. government agencies with illegal activities. The committee reported that the FBI and the CIA had conducted illegal surveillance of several hundred thousand U.S. citizens. The CIA was also charged with illegally plotting to assassinate foreign leaders, such as Salvador Allende, the democratically elected socialist president of Chile. In 1973, Allende was killed in a coup that the CIA secretly helped organize. The Senate committee also reported that the CIA had maintained a secret stockpile of poisons despite a specific presidential order to destroy the substances.
