TV host Dr. Mehmet Oz (R-Pennsylvania), who was endorsed by former President Donald Trump in early April, was attacked by his Republican opponents for not being Republican enough during Monday night's GOP Senate primary debate. Oz went up against David McCormick, Carla Sands, Jeff Bartos and Kathy Barnette in the debate and the candidates discussed a wide range of topics from the 2020 election to trans women in women's sports. McCormick accused Oz of changing his opinion on hot GOP topics such as abortion. “Mehmet has flip-flopped on every major issue, and you can go to his own comments. May 21, 2019, an interview with the Breakfast Club,” McCormick, a former President George W. Bush administration official and the biggest threat to Oz's campaign, said. “He essentially said that he was worried about the pro-life movement that was creating fights, and he was worried about states putting in place pro-life legislation, and he called into question when life begins at conception.” McCormick also brought up another controversial topic Oz had spoken about on his show. “You did an entire show on July 22, 2015, that was about 8-, 7-, 8-, 9-year-old children and you were supporting those conversations about transgender transitions — surgical things, treatments, that would be irreversible," McCormick said. Oz said that he had to speak about all views on network television. Oz touted his endorsement from Trump and used Trump's support as a defense against the accusations. The doctor noted that Trump had deemed him "pro-life." "President Trump doesn't always get the best advice. It's unfortunate but true," Sands, a Trump administration official retorted. Oz stood by Trump as he insisted that "we cannot move on" from the 2020 election. "I have discussed it with President Trump and we cannot move on," Oz said of the 2020 election. "As all the other candidates up here have outlined, under the cover of Covid there were draconian changes made to our voting laws by Democratic leadership, and they have blocked appropriate reviews of some of those decisions. We have to be serious about what happened in 2020, and we won't be able to address that until we can really look under the hood."
