Trump and his wife, first lady Melania Trump, participated in a decades-old tradition known as "flags in."
Every Thursday before the holiday, members of the 3rd U.S. Infantry Regiment, or the Old Guard, honor the nation's fallen heroes by placing American flags at each service member's headstone.
Trump and the first lady each placed three flags at three headstones after making a quiet trip to the hallowed burial ground.
Presidents typically lay a wreath and deliver remarks at the cemetery on Monday, which is Memorial Day, but Trump will be in Japan on a state visit.
