Hillary Clinton hospitalized with blood clot
"In the course of a follow-up exam, Secretary Clinton's doctors discovered a blood clot had formed, stemming from the concussion she sustained several weeks ago," spokesman Philippe Reines said in a statement.
"She is being treated with anti-coagulants and is at NewYork-Presbyterian Hospital so that they can monitor the medication over the next 48 hours," Reines said, adding that doctors would continue to assess her condition.
"They will determine if any further action is required," he said.
U.S. officials said on Dec. 15 that Clinton, 65, who earlier canceled an overseas trip because of a stomach virus, suffered a concussion after fainting due to dehydration.
They have since described her condition as improving and played down suggestions it was more serious.
