Obama Presents Top Honor to Bill Clinton --- WASHINGTON — Standing wordlessly before a flickering flame, their faces etched in the sunlight slanting through a canopy of thinning trees, two Democratic presidents came together Wednesday at Arlington National Cemetery to honor the memory of a third. -- President Obama and former President Bill Clinton walked up a hillside to the grave of John F. Kennedy, where, joined by Michelle Obama and Hillary Rodham Clinton, they laid a wreath to commemorate the 50th anniversary of Kennedy’s death by an assassin’s bullet. -- A military bugler called out taps, the mournful notes resounding on a crisp, clear autumn day that seemed a softer echo of the stark grandeur of the state funeral on Nov. 25, 1963. - More, MARK LANDLER - nytimes
