Former President Trump endorsed Pennsylvania Senate candidate Mehmet Oz on Saturday. “The Great Commonwealth of Pennsylvania has a tremendous opportunity to Save America by electing the brilliant and well-known Dr. Mehmet Oz for the United States Senate,” Trump wrote in a statement that was sent out while the former president was speaking at a rally in North Carolina. A poll from The Hill/Emerson College released this week showed Oz, a celebrity cardiothoracic surgeon, and his primary opponent Dave McCormick being neck-and-neck among likely GOP primary voters.
