John F. Kennedy, the 35th president of the United States, was assassinated at 12:30 p.m. Central Standard Time on Friday, November 22, 1963, in Dealey Plaza, Dallas, Texas. Fatally shot by Lee Harvey Oswald, Kennedy was traveling with his wife, Jacqueline, Texas Governor John Connally, and Connally’s wife, Nellie, in a presidential motorcade. A 10-month investigation from November 1963 to September 1964 by the Warren Commission concluded that Oswald acted alone in shooting Kennedy, and that Jack Ruby also acted alone when he killed Oswald before he could stand trial. Kennedy’s death marked the fourth and most recent assassination of an American President. Vice President Lyndon B. Johnson became president upon Kennedy’s death, taking the constitutionally prescribed oath of office onboard Air Force One at Dallas’s Love Field airport before departing for Washington, D.C.
