Dr. Anthony Fauci on Wednesday repeatedly invoked the Fifth Amendment and declined to answer dozens of questions from senators in a Republican-led committee hearing about his handling of the COVID-19 pandemic.
The decision, at least for now, shielded Fauci from answering questions that could expose him to accusations of lying under oath. Though he received a pardon in early 2025 from Democratic President Joe Biden, some Republicans pursuing a yearslong campaign for his arrest had suggested he could still face charges for any perjury committed during Wednesday’s hearing.
The scientist, who helped lead the nation’s COVID-19 response, was subpoenaed to testify under oath by Republican Sen. Rand Paul of Kentucky, who has long had an antagonistic relationship with Fauci.
In response to angry, sometimes mocking, questions from Republican senators, Fauci declined to answer more than 100 times, injecting new drama into partisan divides that have festered for years about the origins and handling of the pandemic. Fauci himself has become a polarizing figure, even receiving death threats that prompted him to seek security.
In his opening statement, Fauci said Paul has an “obvious obsession with calling for my prosecution.”
“The only conclusion I can reach is that the sole reason he is calling me before this committee is to get me to say something, anything, that could vindicate his repeated public pledges that I end up, in his words, quote, behind bars, unquote.” Fauci said, adding that while it pained him to do so, he was following his attorney’s advice by taking the Fifth.
Republicans accuse Fauci of lying while Democrats say he didn’t deserve that
In the combative hearing, Paul and other Republicans accused Fauci of lying in earlier testimony about the origins of the coronavirus, something the longtime National Institutes of Health scientist has forcefully denied. Democrats called the hearing a politically motivated attempt at entrapping Fauci and praised the scientist for his work during the pandemic.
With Fauci declining to answer questions throughout, Paul dominated the approximately three-hour hearing, listing a litany of accusations and detailed questions about the pandemic.
“Today will be the capstone to Anthony Fauci’s 40 years of abuse of power at NIH,” Paul said. “History will judge, but the facts as we now know them paint a sordid tale of dishonesty, misjudgment and ultimately the hubris, the likes of which the world has never seen.”
In one heated moment of the hearing, Paul ejected Fauci attorney David Schertler from the room after he tried to speak without being recognized. In a statement, Schertler said the removal was “outrageous and demonstrates the completely biased and baseless nature of this proceeding.” In another statement, he called Paul’s accusations about Fauci “false and disgraceful.”
Democratic senators praised Fauci and said he didn’t deserve the treatment he was getting.
“This hearing is designed to entrap you,” said Sen. Maggie Hassan of New Hampshire.
Paul has long argued Fauci should be criminally investigated based on his belief that the scientist was dishonest in previous testimony to Congress.
Paul announced late in the hearing that the committee would vote next week on whether to hold Fauci in contempt for declining to answer questions. The senator did not say whether he would push for a criminal contempt referral to federal prosecutors or another charge.
Paul releases some of Fauci’s diary
Leading up to the hearing, Paul released more than 1,000 pages of Fauci’s personal diary covering the pandemic years. Pointing to some notes about early efforts at understanding how the virus emerged, Paul said on social media that what Fauci “wrote privately and what he told the country are two different stories.”
Some of the diary entries – including Fauci’s uncertainty in the pandemic’s earliest days as scientists around the world raced to understand the new virus and how best to curb it before vaccines could be created – already were reflected in a 2024 memoir and in interviews at the time.
But they have nonetheless drawn attention from people who blame Fauci for mask mandates, school closures and other policies they believe infringed on their rights as hundreds of thousands of people were dying.
Earlier Wednesday, President Donald Trump wrote on social media that he stopped relying on Fauci over the course of the pandemic because he felt the scientist made bad decisions on masks, shutdowns and other issues.
Health Secretary Robert F. Kennedy Jr., a longtime anti-vaccine activist before entering public office, said on social media that his department found the diary entries in government property and gave them to the committee.
Dozens of disease experts defend Fauci
Scientists also scrambled to Fauci’s defense ahead of the unusual hearing — the second time he has been back before Congress to discuss pandemic origins since leaving the government in 2022. While the COVID-19 pandemic introduced him to millions of Americans, he talked the nation through numerous outbreaks over decades, including HIV, Ebola and the 2001 anthrax attacks, while advising seven presidents.
In a public letter, more than 150 infectious-disease experts and other scientists wrote that “no credible evidence has been produced to support these absurd charges” and that they are “urging our elected representatives in Congress stop these witch-hunts.”
Among topics discussed at Wednesday’s hearing was whether NIH-funded research in China may have played a role in how the pandemic started.
Many scientists believe the virus most likely emerged in nature and jumped from animals to people, coming to light when it spread at a wildlife market in the Chinese city of Wuhan. There’s no new scientific information supporting that the virus might instead have leaked from a laboratory, a theory Paul champions. A GOP-led subcommittee that studied the question in 2024 did not find any evidence linking Fauci to wrongdoing.
Fauci has long said publicly that he was open to both theories but that there’s more evidence supporting COVID-19’s natural origins.
Republicans also have accused Fauci of lying about whether his agency funded what’s known as gain of function research — the practice of enhancing a virus in a lab to study its potential real-world impact — at a lab in Wuhan.
The NIH for years gave grants to a New York nonprofit called EcoHealth Alliance, which used some of the funds to work with a Chinese lab studying coronaviruses commonly carried by bats. But the definition of gain of function covers both general research and especially risky experiments to enhance the ability of potential pandemic viruses to spread or cause severe disease in humans. Fauci has previously stressed he was using the risky experiment definition and that “it would be molecularly impossible” for those bat virus experiments to have turned into the pandemic virus.
Trump, a Republican, last year paused some federally funded gain of function research, and on Tuesday his administration announced new rules to tighten oversight.
