The nominee, a surgeon at Johns Hopkins, has criticized the use of pesticides on food and the industry turning against “natural fat.”

President-elect Donald Trump has selected Marty Makary, a Johns Hopkins surgeon who criticized the Biden administration’s Covid response, to lead the FDA. “FDA has lost the trust of Americans, and has lost sight of its primary goal as a regulator,” Trump said in a statement late Friday, adding Makary would “course-correct” the agency if confirmed.

Martin Makary was known for his contrarian stance during the Covid pandemic, as he questioned the necessity of masking. He was not opposed to the vaccine but expressed reservations about booster shots for young children.
