 O'Sullivan stated that while researching a screenplay based on the Manchurian candidate theory for the assassination of Robert Kennedy, he "uncovered new video and photographic evidence suggesting that three senior CIA operatives were behind the killing".He claimed that three men seen in video and photographs of the Ambassador Hotel immediately before and after the assassination were positively identified as CIA operatives Gordon Campbell, George Joannides, and Morales.Several people who had known Morales, including family members, were adamant that he was not the man who O'Sullivan said was Morales.
