Republican Pennsylvania senatorial candidate Mehmet Oz is raising eyebrows with promises to “defend the sanctity of life” in light of past comments he made suggesting he was open to abortions.

“I will be a bold voice in the Senate and a proud champion for the pro-life movement,” Oz wrote in a Washington Examiner op-ed published Wednesday. “I won’t ever shy away from sharing my pro-life beliefs, even as pro-abortion advocates in medicine, the media, and Big Tech try to silence me.”

“I’ve taken on the establishment countless times before, and I am ready to do it again for the most vulnerable,” he added. “I will always defend the sanctity of life.”
