In 1956 Kennedy moved his growing family outside Washington to a house called Hickory Hill , which he purchased from his brother John . This enormous 13-bedroom , 13-bath home was situated on in McLean , Virginia . Kennedy went on to work as an aide to Adlai Stevenson during the 1956 presidential election which helped him learn how national campaigns worked , in preparation for a future run by his brother , Jack . Unimpressed with Stevenson , he reportedly voted for incumbent Dwight D. Eisenhower . Kennedy was also a delegate at the 1956 Democratic National Convention , having replaced Tip O'Neil at the request of his brother John , joining in what was ultimately an unsuccessful effort to help JFK get the vice presidential nomination . Shortly after this , following instructions by his father , Kennedy tried making amends with J. Edgar Hoover . There seemed to be some improvement in their interactions , which came to be seen as " elemental political necessity " by Kennedy . This later changed after Kennedy was appointed attorney general , where Hoover saw him as an " unprecedented threat "
