Dr. Mehmet Oz, the celebrity heart surgeon endorsed by former President Donald Trump, officially won Pennsylvania’s Republican U.S. Senate primary on Wednesday, narrowly defeating former hedge fund CEO David McCormick after a dayslong statewide recount buffeted by litigation that reached the nation’s highest court. The recount determined that Oz had eked out a victory over McCormick by 951 votes out of more than 1.3 million cast in the May 17 primary election. It came several days after McCormick conceded the race, acknowledging that he was not getting the boost he needed to close the gap. In November’s general election, Oz will face Democratic Lt. Gov. John Fetterman, who is off the campaign trail while he recovers from a stroke and a serious heart condition.
