November 1988 Anderson hosted a two-hour prime-time television special entitled American Expose: Who Murdered JFK? The program asserted that the assassination of John F. Kennedy was a conspiracy involving an alliance between organized crime and the Cuban government, and that the Warren Commission did not publicly reveal the true findings. Anderson's theory was based on interviews with mobster John Roselli who – prior to his death 12 years earlier – said he learned of a conspiracy through mob sources. Anderson's conversations with Roselli were re-enacted with an actor portraying Roselli. According to Anderson, Cuban leader Fidel Castro wanted Kennedy killed in retaliation for CIA plots to kill Castro, and leaders of La Cosa Nostra in the United States opposed him due to his brother Robert F. Kennedy's efforts as US Attorney General against organized crime. He said that Santo Trafficante, Carlos Marcello, and Jimmy Hoffa had the "motive and means to kill the president", and reiterated reports connecting Lee Harvey Oswald and Jack Ruby to the mob. Anderson also alleged that President Lyndon B. Johnson covered up the conspiracy for fear that public knowledge of the CIA plots would trigger war with the Soviet Union. According to Anderson's report, private photographic analysts concluded that the shot that killed Kennedy came from the front, and that E. Howard Hunt and James Earl Ray were depicted in photographs of the "three tramps". Hunt denied the charge on the program and said he had witnesses who could prove he was not in Dallas. An Associated Press (AP) writer described it as a "bizarre allegation," to which Anderson provided "no explanation of their alleged connection". Chicago Tribune columnist Steve Daily called the program "limp" and said Anderson's conclusion that organized crime was responsible for the assassination was based "on circumstantial evidence and the word of dead gangster Johnny Roselli." Howard Rosenberg of the Los Angeles Times wrote that it was "tawdry and strident" and said Anderson's "so-called evidence was unclear, unconvincing and untrustworthy." The Deseret News said Anderson was trying to "rewrite history". Capitol security stunt To demonstrate the weak security within the U.S. Capitol, in 1989, Anderson brought a gun to an interview in the office of Bob Dole, Senate minority leader. He was reprimanded and Congress passed a change of rules for reporters' access to the Capitol and politicians.
