Robert Francis Kennedy (November 20, 1925 – June 6, 1968), also known by his initials RFK and by the nickname Bobby,[1][2] was an American lawyer and politician who served as the 64th United States Attorney General from January 1961 to September 1964, and as a U.S. Senator from New York from January 1965 until his assassination in June 1968. He was, like his brothers John and Edward, a prominent member of the Democratic Party and has come to be viewed by some historians as an icon of modern American liberalism.[3]
