Jack Ruby, a Dallas nightclub owner, killed Lee Harvey Oswald, who the Warren Commission concluded was the lone gunman in the slaying of John F. Kennedy.
In a videotaped statement, Ruby said, “When I mentioned about Adlai Stevenson, if he was Vice President there would never have been an assassination of our beloved President Kennedy.” Asked if he would explain it again Ruby continued “Well the answer is the man in office now.” – that man was Lyndon B. Johnson.
Later, in a hand-written note, Ruby wrote, “Isn’t it strange that Oswald, who hasn’t worked a lick most of his life, should be fortunate enough to get a job at the Book Building two weeks before the President himself didn’t know as to when he was to visit Dallas, now where would a jerk like Oswald get the information that the President was coming to Dallas?”
He continued on, “Only one person could have had that information, and that man was Johnson who knew weeks in advance as to what was going to happen, because he is the one who was going to arrange the trip for the President, this had been planned long before the President himself knew about, so you can figure that one out.”
He wrote further, “The only one who gained by the shooting of the President was Johnson, and he was in a car in the rear and safe when the shooting took place. What would the Russians, Castro or anyone else have to gain by eliminating the President? If Johnson was so heartbroken over Kennedy, why didn’t he do something for Robert Kennedy? All he did was snub him.”
Jacqueline Kennedy was aware of Johnson’s hatred for her husband and his brother, often referring to the pair as members of the Irish mafia.
