About Robert F. Kennedy
Robert Francis "Bobby" Kennedy (November 20, 1925–June 6, 1968), also called RFK, was an American politician. He was United States Attorney General from 1961 to 1964 and a United States Senator from New York from 1965 until his assassination in 1968. He was one of the younger brothers of U.S. President John F. Kennedy and also one of his most trusted advisers, working closely with the president during the Cuban Missile Crisis. After his brother's November 1963 assassination, Kennedy continued as Attorney General under President Lyndon B. Johnson for nine months. He resigned in September 1964 and was elected to the United States Senate from New York that November. He broke with Johnson over the Vietnam War, among other issues.
