Kennedy was asked by Democratic Party leaders to introduce a film about his late brother at the 1964 party convention . When he was introduced , the crowd , including party bosses , elected officials , and delegates , applauded thunderously and tearfully for a full 22 minutes before they would let him speak . He was close to breaking down before he spoke about his brother 's vision for both the party and the nation and recited a quote from Shakespeare 's '' Romeo and Juliet '' ( 3.2 ) that Jacqueline had given him : The ten-month investigation by the Warren Commission of 1963 – 1964 concluded that the president had been assassinated by Lee Harvey Oswald and that Oswald had acted alone . On September 27 , 1964 , Kennedy issued a statement through his New York campaign office : " As I said in Poland last summer , I am convinced Oswald was solely responsible for what happened and that he did not have any outside help or assistance . He was a malcontent who could not get along here or in the Soviet Union . " He added , " I have not read the report , nor do I intend to . But I have been briefed on it and I am completely satisfied that the Commission investigated every lead and examined every piece of evidence . The Commission 's inquiry was thorough and conscientious . " After a meeting with Kennedy in 1966 , Arthur M. Schlesinger Jr. wrote : " It is evident that he believes that the Warren Commission 's report was a poor job and will not endorse it , but that he is unwilling to criticize it and thereby reopen the whole tragic business . " Jerry Bruno , an " advance man " for JFK who also worked on RFK 's 1968 presidential campaign , would later state in 1993 : " I talked to Robert Kennedy many times about the Warren Commission , and he never doubted their result . " In a 2013 interview with CBS journalist Charlie Rose , son Robert F. Kennedy Jr. stated that his father was " fairly convinced " that others besides Oswald were involved in his brother 's assassination and that he privately believed the Commission 's report was a " shoddy piece of craftsmanship "
