WASHINGTON (AP) - Secretary of State Hillary Rodham Clinton has been admitted to a New York hospital after the discovery of a blood clot stemming from the concussion she sustained earlier this month.
 
Clinton spokesman Philippe Reines says her doctors discovered the clot during a follow-up exam Sunday. Reines would not elaborate on the location of the clot but says Clinton is being treated with anti-coagulants.
 
Clinton was admitted to New York-Presbyterian Hospital so doctors can monitor the medication over the next 48 hours.
 
Reines says doctors will continue to assess Clinton's condition, "including other issues associated with her concussion."
 
65-year-old Clinton fell and suffered a concussion while at home alone in mid-December as she recovered from a stomach virus that left her severely dehydrated.
 
The concussion was diagnosed Dec. 13 and Clinton was forced to cancel a trip to North Africa and the Middle East that had been planned for the next week.
