President Joe Biden’s chief medical adviser, Anthony Fauci, said that he will retire by the end of Biden’s term.

“By the time we get to the end of the Biden administration term, I feel it would be time for me to step down from this position,” Fauci told the Washington Post on Monday.

The news of Fauci’s retirement plans was first reported by Politico.

“We’re in a pattern now. If somebody says, ‘You’ll leave when we don’t have COVID anymore,’ then I will be 105,” Fauci told Politico. “I think we’re going to be living with this.”

Fauci has advised seven different presidents over five decades. He’s served as the director of the National Institute of Allergy and Infectious Diseases (NIAID) since 1984.

After the Politico article was published, Fauci clarified his plans during an appearance on CNN.

“What happened is that I gave an interview with a reporter, and they said, ‘You know, you’re going to have to step down some time, you can’t be in this job forever.’ I said, ‘You’re absolutely right, I can’t be in this job forever.’ And I don’t anticipate I’ll be in this job at the end of the first term of President Biden, which is January 2025,” Fauci told CNN’s Kate Bolduan.

“Somehow that got interpreted that it’s announcing my retirement. I just said that it is extremely unlikely, in fact, for sure that I’m not going to be here beyond January 2025,” Fauci said.

“So sometime between now and January 2025, you can guarantee I’ll step down.”

Upon his retirement, Fauci will earn the largest federal retirement package in U.S. history, with his annual pension exceeding $350,000.

For two years in a row, Fauci the was the most highly-compensated federal employee — even earning more than the president.
