Clinton is slated to attend a meeting with assistant secretaries of state this morning, according to the department's schedule.
She was discharged from a New York hospital Wednesday, three days after she was admitted for the treatment of a blood clot in a vein between her skull and brain.
Clinton's troubles started in December when she fainted from dehydration caused by the flu.
Doctors found the clot during a medical test related to a concussion.
Clinton was treated with blood thinners to dissolve the clot.
