Video: Barack Obama and Bill Clinton lay wreath at John F. Kennedy's grave First Lady Michelle Obama and former Secretary of State Hillary Rodham Clinton joined the two presidents to place a wreath near the eternal flame that marks Kennedy's grave site. President Obama and Mr Clinton placed their hands over their hearts as a bugler played taps near an American flag at half-staff. Barack Obama made no public comments, but greeted Kennedy relatives, gathered to honour his legacy, ahead of the 50th anniversary of his assassination on Friday. Kennedy established the modern version of the medal, but was assassinated by Lee Harvey Oswald in Dallas on November 22, 1963, two weeks before he planned to honour the inaugural group of recipients.
