The Biden administration is expected to remove Dr. Mehmet Oz and Herschel Walker from a federal advisory committee after both failed to resign by a Wednesday deadline.
Oz, a celebrity doctor, and Walker, a former NFL star, were each sent a letter from the White House on Wednesday asking them to resign from the President's Council on Sports, Fitness and Nutrition by the end of the day, warning that failure to step down would result in termination, NBC News reported.
Oz and Walker were initially appointed to the council in 2018 and then reappointed to two-year terms in December 2020 by then President Donald Trump.
A White House official told CNN that the resignation requests were made because Oz and Walker are running for federal office, and the administration prohibits candidates for federal office from serving on boards and commissions.
Oz is running for a U.S. Senate seat in Pennsylvania, while Walker is running for a U.S. Senate seat in Georgia.
In response to the letter, Oz posted a video to Twitter saying he had no intention of resigning and that Biden would have to fire him.
"I am beyond grateful to President Trump for appointing me to this very prestigious and important position. I am also grateful to my colleagues on the committee and council, and the amazing accomplishments we were able to achieve. I've got no intentions, my friends, of resigning. None,” he said.
"If President Biden wants to politicize health, he'll have to fire me. Let Americans see how truly petty and political he truly is," Oz added.
Walker also responded: "I’m not a quitter so you are going to have to fire me."
Meantime, the White House announced that World Central Kitchen founder and chef José Andrés and WNBA star Elena Delle Donne were appointed as co-chairs of the President's Council on Sports, Fitness and Nutrition.
The committee, made up of about 30 members, aims to promote healthy eating and physical activity for all Americans.
"Completely honored by this appointment," Donne wrote on Twitter. "I look forward to building awareness around the best ways to take care of our minds and bodies."
Andres also responded: "I'm excited to get to work putting nutrition at the heart of creating a healthy, prosperous & more equitable future for America and the world, where food brings us together."
