Lt. Gov. John Fetterman, the Democratic nominee in the state’s high-profile U.S. Senate contest, has been released from the hospital after a stay of more than a week following a stroke, his wife and his campaign said Sunday. Fetterman, 52, won the Democratic nomination while in the hospital, easily beating U.S. Rep. Conor Lamb, just hours after undergoing surgery to implant a pacemaker with a defibrillator to help him recover. Fetterman has said the stroke was caused by a heart condition called atrial fibrillation.
