(CNN) - Secretary of State Hillary Clinton is sprinting to the finish as America's top diplomat, preparing for a high-profile hearing on the deadly Benghazi attack and two signature opportunities to have the last word on her tenure.

Clinton, who returned to work last week after battling a virus and a blood clot, is aggressively tackling her work load, even as official Washington gets ready to pause for President Barack Obama's second inaugural on Monday.
