President Barack Obama, accompanied by Secretary of State Hillary Rodham Clinton, speaks during the Transfer of Remains Ceremony, Friday, Sept. 14, 2012, at Andrews Air Force Base, Md., marking the return to the United States of the remains of the four Americans killed this week in Benghazi, Libya. Obama said in a Rose Garden statement after the attack that those responsible would be brought to justice. That may not be swift. Building a clearer picture of what happened will take more time, and possibly more people, U.S. officials said Friday. (AP Photo/Carolyn Kaster)
