Robert Francis "Bobby" Kennedy (November 20, 1925 – June 6, 1968), also referred to by his initials RFK, was an American politician, a Democratic senator from New York, and a noted civil-rights activist. An icon of modern American liberalism and a member of the Kennedy family, he was a younger brother of President John F. Kennedy, and he served as the president's chief advisor during his presidency. From 1961 to 1964 he served as the U.S. Attorney General.
Following his brother John's assassination, on November 22, 1963, Kennedy continued to serve as the Attorney General under President Lyndon B. Johnson for nine months. There long had been bad blood between them, so in September 1964 Kennedy resigned to seek a U.S. Senate seat from New York, which he won in November. Within a few years he publicly split with Johnson over the Vietnam War.
In March 1968 Kennedy began a campaign for the presidency and was a front-running candidate of the Democratic Party, appealing especially to black, hispanic and Catholic voters. In the California presidential primary, on June 4, Kennedy defeated Eugene McCarthy, the hero of the New Left and student elements in the Democratic Party. That night Kennedy was shot by Sirhan Sirhan, a Palestinian Arab. Mortally wounded, he survived nearly 26 hours, then died early in the morning of June 6.
