Lee Harvey Oswald's honorable discharge from the U.S. Marine Corps Reserve is changed to an "undesirable discharge," based on "reliable information which indicated that he had renounced his U.S. citizenship with the intentions of becoming a permanent citizen of the Union of Soviet Socialists Republic." (This 1960 photo is from when Oswald worked at a radio-television factory in Minsk.) The same day, Democratic presidential candidate John F. Kennedy campaigns in Dallas, Texas; his motorcade takes him through Dealey Plaza.
