The "Chappaquiddick incident" refers to the death of Mary Jo Kopechne, a former campaign worker for the assassinated U.S. Senator Robert F. Kennedy of New York. Kopechne's dead body was discovered inside an overturned car belonging to Senator Ted Kennedy in a channel on Chappaquiddick Island. The incident became a national scandal and may have affected the Senator's decision not to run for President in 1972.
