A week after the assassination, President Lyndon B. Johnson issued an executive order that created the Warren Commission—led by Chief Justice Earl Warren—to investigate the assassination. Ten months later, the Commission issued its report finding that Lee Harvey Oswald had acted alone when he assassinated President Kennedy. Kennedy Onassis did not care about the investigation. She said that even if they had the right suspect, it would not bring her husband back. She gave her testimony to the commission detailing the events of her husband's assassination.
