In 1964, three civil rights workers and voter registration activists were found dead in Mississippi. They had disappeared on June 21, 1964, abducted by a local police officer and subsequently murdered by a Ku Klux Klan death squad.

In 1964, North Vietnamese gunboats allegedly fired on an American destroyer in the Gulf of Tonkin. Another incident in the Tonkin Gulf was supposed to have occurred on August 2, 1964. Together, these 'attacks" motivated the United States Congress to pass the Gulf of Tonkin Resolution (Southeast Asia Resolution, P.L. 88-408). The Resolution was an enabling act which authorized President Lyndon Johnson to use American troops to contest Communist aggression in Southeast Asia. This troop usage did not require Congress to pass a Declaration of War. The American government's abuse of this delegated authority under Presidents Johnson and Nixon led to the passage of the War Powers Resolution of 1973 (50 U.S.C. 1541–1548).
