Dr. Anthony Fauci, the nation's top epidemiologist, had a vocal cord polyp removed via outpatient surgery Thursday morning, Fox News has confirmed.

As a result of the surgery, Fauci will have to rest "his voice for a few days," according to a spokesperson. CNN first reported the story.

Fauci, the director of the National Institute of Allergy and Infectious Diseases, has been one of the highest-profile figures as the Trump administration has responded to the coronavirus pandemic. He was a regular at the White House Coronavirus Task Force briefings earlier in the pandemic and has since been a regular in TV interviews, social media interviews with celebrities like Matthew McConaughey and in congressional hearings.

But, Fauci more recently has fallen out of the good graces of some members of the administration, most notably trade adviser Peter Navarro, who accused him of being “wrong” on the coronavirus at every step in a stunning op-ed published by USA Today.

“Dr. Anthony Fauci has a good bedside manner with the public, but he has been wrong about everything I have interacted with him on,” Navarro wrote.

“Ultimately, it hurts the president to do that,” Fauci told The Atlantic. “When the staff lets out something like that and the entire scientific and press community push back on it, it ultimately hurts the president.”

President Trump himself said after the Navarro op-ed that he's had a "very good relationship" with Fauci and recently cited Fauci's assessment that in-person voting in November could take place with proper precautions.

Fauci often has been critical of states that he said reopened from their pandemic-related shutdowns faster than they should have under guidelines released by the Trump administration. He also last week said that he favored a national mask mandate.

"You make a really good point that is the subject of a lot of debate," he said in response to a question from McConaughey on Instagram Live. "My recommendation as you probably know because I've said it publicly so many times is that absolutely we should have universal wearing of masks."

Fauci added: "The difficulty with mandates is that it tends to be a pushback about, 'do you have to waste time enforcing it, or can you really use the power of persuasion from the leadership, everybody doing it, because it's so important?' And there's a debate whether you get any extra mileage out of mandating it. Myself, personally, I would say everybody should have to use it."
