"In the course of a follow-up exam today, Secretary Clinton's doctors discovered a blood clot had formed, stemming from the concussion she sustained several weeks ago. 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," a spokesman for the former first lady said yesterday in a statement.

"EXCLUSIVE! HILLARY CLINTON BRAIN CRISIS," the National Enquirer headline reads. "Only days after The ENQUIRER exclusively reported that Secretary of State HILLARY CLINTON was at the center of a shocking brain cancer drama and was undergoing extensive secret medical tests, her reps went public with the news on Sunday night Dec. 30 that she was indeed hospitalized in New York City and disclosed that she was battling a blood clot that had formed following her head concussion earlier this month!"
