President-elect Donald Trump has nominated a critic of COVID-19 health measures to lead the Food and Drug Administration.

Maryland scholars on Monday alternately described President-elect Donald Trump’s pick to lead the U.S. Food and Drug Administration — Dr. Marty Makary, a Johns Hopkins researcher, surgeon and author — as a “courageous leader” and a “reasonable choice,” who nevertheless espouses some “worrisome” views.

A prolific medical research and author, Martin Makary criticized the FDA and CDC for their decision-making during the pandemic, although he describes himself as pro-vaccine.
