Hillary Clinton wraps up her tenure as secretary of state. The former Senator, First Lady and one time Presidential candidate traveled more that 956,000 miles ... visiting a record 112 countries as secretary of state. Graham Allison of Harvard University: (SOUNDBITE) (English) GRAHAM ALLISON, PROFESSOR, JOHN F. KENNEDY SCHOOL OF GOVERNMENT, HARVARD UNIVERSITY, SAYING: "She was a political heavyweight. Second, she was a rock star in representing the U.S. around the world and third, she is incredibly hardworking and you can see all those features in the course of her four years." One stain on her record: The deadly attack on the U.S. mission in Benghazi that killed four people including Ambassador Christopher Stevens. She offered her own defense in her final Congressional testimony. (SOUNDBITE) (English) U.S. SECRETARY OF STATE HILLARY CLINTON SAYING: "With all due respect, the fact is that we had four dead Americans. Was it because of a protest? Or was it because some guys out for a walk one night who decided they would go kill some Americans? What difference at this point does it make? It is our job to figure out what happened and do everything we can to prevent it from ever happening again, Senator." The question now is whether she will run for president in 2016. A Public Policy Polling survey found that 57 percent of Democrats would like her to run. So far she is not showing her hand about her future.
