CBS: Thomas Pickering – the former UN ambassador who along with former Joint Chiefs of Staff chairman Adm. Mike Mullen prepared the Accountability Review Board report on the State Department’s handling of the Sept. 11 attack in Benghazi, Libya – says he didn’t think it was necessary to interview former Secretary of State Hillary Clinton “because in fact we knew where the responsibility rested.”
