Teresa Heinz Kerry, wife of Secretary of State John Kerry, is in critical but stable condition after being taken by ambulance from the couple's Nantucket, Mass. home to a hospital on Sunday afternoon, sources close to the family told NBC News.
A spokesman for Nantucket Cottage Hospital said Heinz Kerry, 74, was admitted to the emergency room around 3:30p.m. but gave no more public information about her condition.
Heinz Kerry, a breast cancer survivor, is the mother of three adult sons from her marriage to the late Pennsylvania Sen. John Heinz who died in a plane crash in 1991.
Sec. Kerry has been in Nantucket since returning from the Middle East on Wednesday.
Heinz Kerry is a longtime activist on environmental causes and leads the Heinz Family Foundation.
