U.S. President Barack Obama watches as the body of an American killed in Benghazi this week is placed in a hearse during a return of remains ceremony at Andrews Air Force Base near Washington, September 14, 2012. Obama arrived at Andrews Air Force Base on Friday to lead a ceremony honoring the return of the remains of the U.S. Ambassador Christopher Stevens and three other Americans killed in an attack in Libya this week. Stevens and the other Americans died after gunmen attacked the lightly fortified U.S. consulate and a safe house refuge in Benghazi on Tuesday night.
