Dr. Anthony Fauci, the chief medical advisor to the president and director of the National Institute of Allergy and Infectious Diseases, indicated earlier this week that he plans to retire by the end of Joe Biden’s first term.

An analysis by OpenTheBooks estimated Fauci will receive the largest federal retirement package in history, with a first-year pension payout exceeding $414,000.

By next year, Fauci could be getting over half a million dollars, according to Andrzejewski’s analysis.

Since 2019, Fauci has been the highest paid federal government employee, “out earning the president, four-star generals and roughly 4.3 million of his colleagues,” Andrzejewski wrote.

Today, Fauci earns an annual salary of $480,654, more than his former boss, now-retired NIH Director Francis Collins, more than Collins’s old boss, Health and Human Services Secretary Xavier Becerra and even more than Becerra’s boss, the president, according to Andrzejewski.

For context, Joe Biden makes $400,000 a year as president.

Fauci’s large salary dates back to the George W. Bush administration, according to Andrzejewski, who reports to have unearthed a memo outlining a “permanent pay adjustment” for Fauci’s biodefense work.

Dr. Fauci is the 32nd-most cited living researcher, according to an analysis of Google Scholar citations, Andrzejewski wrote last year in a column for Forbes about Fauci’s earnings. Polling has also shown Fauci is the most trusted public figure in the U.S. for information on the pandemic and Covid-19 vaccines, he added.

In 2020, actor Matthew McConaughey asked Fauci during an interview if he had millions of dollars invested in COVID vaccines.

Laughing, Fauci responded, “Matthew, no, I got zero! I’m a government worker. I have a government salary. That’s it.”

According to financial records, Fauci’s household in total made nearly $1.8 million in 2020, Andrzejewski wrote in a separate column for Forbes.
