U.S. Secretary of State Hillary Clinton has been hospitalized with a blood clot after a recent concussion.
The State Department says Clinton's doctors found the clot in a follow-up exam Sunday. They said it was connected to the concussion she suffered after a fall several weeks ago.
Clinton is being treated with anti-clotting medication at New York's Presbyterian Hospital. She is expected to remain there under observation for the next two days.
The statement said Clinton's doctors will continue to assess her condition and determine if any further action is required.
Clinton has been ill in recent weeks, struggling with a stomach virus that forced her to cancel some public appearances and travel plans. On December 21, she became dehydrated and fainted, suffering a concussion in the fall.
Until Sunday, she had been recovering at home.
