Sen. Susan Collins, R-Maine, ranking Republican on the Senate Homeland Security and Governmental Affairs Committee walks to a meeting on Capitol Hill in Washington, Wednesday, Nov. 28, 2012, for a meeting with UN Ambassador Susan Rice. Rice continued her fight Wednesday to win over skeptics in the Senate who could block her chances at becoming the next U.S. secretary of state, while Republican lawmakers said they were even more troubled after face-to-face meetings with her over the handling of the Sept. 11 deadly attack on the U.S. Consulate in Benghazi, Libya.
