U.S. Secretary of State John Kerry's wife, Teresa Heinz Kerry, 74, is in critical, but stable condition at Massachusetts General Hospital, several sources confirm.
Heinz Kerry, who was treated for breast cancer in 2009, was admitted Sunday.
John Kerry's personal spokesman Glen Johnson told ABC News:
"Late Sunday afternoon, Mrs. Teresa Heinz Kerry was taken by ambulance to Nantucket Cottage Hospital, accompanied by her husband, Secretary of State John Kerry."
"Once doctors had stabilized her condition, she was transferred to Massachusetts General Hospital in Boston, again accompanied by the Secretary."
