ABC News last night said there is no truth to a report that Jacqueline Kennedy Onassis believed then US vice-president Lyndon Johnson was involved in the assassination of her husband, President John F Kennedy.

JACKIE KENNEDY had a steamy four-year affair with Bobby Kennedy after JFK’s assassination, according to a new book.

Broadcaster ABC made editing changes to its controversial mini-series The Path to 9/11, after former Clinton administration officials complained that scenes about them were fabricated.

THE origin of what historian Arthur Schlesinger called the Imperial Presidency now expanding the American empire under George W Bush can be traced back to the 1960s and Vietnam, but might never have emerged if JFK had survived Dallas.
