Dr. Mehmet Oz, the celebrity heart surgeon endorsed by former President Donald Trump, won Pennsylvania's Republican U.S. Senate primary on Wednesday, narrowly defeating former hedge fund CEO David McCormick after a dayslong recount.
Oz will face Democratic Lt. Gov. John Fetterman in November in a race that could help determine control of the closely divided Senate. Democrats view it as perhaps their best opportunity to pick up a seat in the race to replace retiring two-term Republican Sen. Pat Toomey.
