Justice Ruth Bader Ginsburg undergoes medical procedure at New York hospital

Justice Ruth Ginsburg underwent a ’minimally invasive’ procedure Wednesday on a bile duct stent and is expected to be released from the hospital by the end of the week. Earlier this month, Ginsburg, 87, had another procedure at Johns Hopkins in Baltimore to clean out the stent. She also went to the hospital in mid-July to have gallstones removed and for the treatment of a suspected infection.
