ABC News is reporting that former President Bill Clinton has been hospitalized in NYC. Clinton, 63, was reportedly rushed to Columbia Presbyterian Hospital in Manhattan "for a condition related to his heart." ABC News' chief political correspondent George Stephanopoulos hears that he was taken to the hospital "likely for a stent procedure." (A stent is small mesh tube that is used to treat narrowed or weakened arteries; Clinton previously had heart surgery in 2004. )

The seriousness of his condition is unknown, but a source tells MSNBC Clinton experienced chest pains before being taken in. NBC also reports that Clinton was originally scheduled to come in to the hospital Wednesday, having called the head of cardiology to say he wasn't feeling well, but postponed the appointment. And sources tell ABC News that Secretary of State Hillary Clinton was seen leaving the Oval Office a short time ago and did not seem "too concerned" or "in a rush." The State Department says she's headed to NYC now.

Douglas Band, counselor to Mr. Clinton, just issued this statement: "Today President Bill Clinton was admitted to the Columbia Campus of New York Presbyterian Hospital after feeling discomfort in his chest. Following a visit to his cardiologist, he underwent a procedure to place two stents in one of his coronary arteries. President Clinton is in good spirits, and will continue to focus on the work of his Foundation and Haiti’s relief and long-term recovery efforts. In 2004, President Clinton underwent a successful quadruple bypass operation to free four blocked arteries."
