"Her doctors will continue to assess her condition, including other issues associated with her concussion," her spokesman, Philippe Reines, said in a statement. "They will determine if any further action is required."
Clinton fainted and suffered a concussion in mid-December when she was home recovering from a stomach virus. The concussion was diagnosed on Dec. 13, and she was forced to cancel several trips.
