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."
Hospital spokesman Noah Brown told The AP that Heinz Kerry is in critical, but stable condition. The reason for her hospitalization is unknown.
Heinz Kerry, a businesswoman and philanthropist, married John Kerry, who served as U.S. Senator from Massachusetts from 1985-2013, in 1995.
She was previously married to her first husband, the late John Heinz, heir to the ketchup and condiment company, before he died in a 1991 plane crash.
She has three sons with Heinz: John, Andre and Christopher.
Heinz Kerry joined Kerry on his 2004 presidential campaign, where he ran alongside vice presidential candidate John Edwards on the Democratic ticket.
The pair ultimately lost to George W. Bush and Dick Cheney.
In 2009, she survived breast cancer after the disease was detected during an annual mammogram. She underwent lumpectomies in both breasts.
We wish her nothing but the best.
