WASHINGTON (AP) -- Supreme Court Justice Ruth Bader Ginsburg has had surgery to place a stent in her right coronary artery.
Court spokeswoman Kathy Arberg says the 81-year-old Ginsburg had the procedure Wednesday morning after a coronary blockage was discovered.
Arberg says Ginsburg had some discomfort Tuesday night during routine exercise and was taken to the hospital.
The justice is expected to leave the hospital in the next 48 hours.
Ginsberg has been on the court since 1993.
