Clinton formally resigns as secretary of state
Hillary Rodham Clinton formally resigned Friday as the 67th US secretary of state, capping a four-year tenure in the office that saw her shatter previous records for the number of countries visited.


In a letter sent to President Barack Obama shortly before she was to leave the State Department for the last time in her official capacity, Clinton thanked her former foe for the 2008 Democratic presidential nomination for the opportunity to serve in his administration. Clinton said it had been an honor to be part of his cabinet and that she remained convinced of the "strength and staying power" of American global leadership. (AP)
