When the bodies of Ambassador Christopher Stevens and three other Americans killed in Benghazi, Libya, arrived at Andrews Air Force Base after the Sept. 11 attack, they were greeted by the president, the vice president and the secretaries of state and defense. Conspicuously absent was CIA Director David Petraeus.
Officials close to Mr. Petraeus say he stayed away in an effort to conceal the agency's role in collecting intelligence and providing security in Benghazi.
