Secretary of State Hillary Clinton has been admitted to a hospital for a blood clot "stemming from" a concussion earlier this month, Clinton spokesman Philippe Reines says. In a statement, Reines says doctors found the clot during a follow-up exam on Sunday.
"She is being treated with anti-coagulants and is at New York-Presbyterian Hospital so that they can monitor the medication over the next 48 hours," he says.
Clinton had been expected to return to work this coming week. CBS News reports:
"Aides and doctors say Clinton contracted a stomach virus in early December and became dehydrated, then fainted, fell and hit her head. She was diagnosed with a concussion on Dec. 13 and hasn't been seen in public since."
