FILE - In this Jan. 23, 2013, file photo, Secretary of State Hillary Rodham Clinton testifies on Capitol Hill in Washington, on the deadly September attack on the U.S. diplomatic mission in Benghazi, Libya, that killed Ambassador Chris Stevens and three other Americans. Clinton’s plan for 2013 was simple. She’d embark on an epic swansong around the world as secretary of state, a dizzying itinerary of east-west and north-south flights that would take her past 1 million miles in the air at the helm of American diplomacy and perhaps break her own record of 112 countries visited while in the post. Her health got in the way and she was sidelined by circumstances beyond her control. (AP Photo/Pablo Martinez Monsivais)
