According to tapes recorded by Jacqueline Kennedy-Onassis, she believed Vice President Lyndon B. Johnson was behind the assassination of her husband, President John F. Kennedy.

The Daily Mail reports that the tapes recorded just months after JFK's death have Jackie O revealing that she believed then-Vice President Johnson and businessmen in the South were involved in the Nov. 22, 1963 assassination in Dallas, Texas. 

"The tabloid reports about the content of the tapes are totally erroneous," an ABC News spokesperson said in a statement to FoxNews.com. "ABC News isn't releasing any content from those tapes until mid-September at which point it will be clear how off base these reports are. The actual content of the tapes provide unique and important insight into our recent past from one of the most fascinating and influential First Ladies in American history." 

Kennedy-Onassis thought gunman Lee Harvey Oswald (long believed to be a lone assassin) was part of a larger conspiracy involving Johnson, according to the Daily Mail. The tapes are also reported to reveal that Kennedy-Onassis had an affair with actor William Holden (The Wild Bunch) in retaliation to her husband's reported indiscretions.

The tapes, which were sealed in a vault at the Kennedy Library in Boston, were supposed to be released 50 years after Kennedy-Onassis' 1994 death. However, her daughter, Caroline Kennedy, reportedly agreed to their early release.

The tapes are set to be released by ABC News on a yet to be announced date.
