TheRepublican-led hearing- convened to scrutinize Fauci's management of the pandemic and the origins of COVID-19 - was thelatest chapter in a political storythat began in 2020, when uncertainty, fear and frustration with the government becameentangled with conspiracy theories.

In the past six years, some of these theories have emerged from the margins of the internet and made their way intoRepublican politics, theMAGA movement,anti-vaccine communitiesand even white-nationalistextremist networks.

Conspiracy theories do not simply explain events, theyidentify villains- and Fauci has become one of the most popular in this particular story.

In the years since the pandemic, U.S. Sen. Rand Paul and others haveaccused Fauciof many things, but the central conspiracy accusation is that Faucihelped enable the COVID-19 pandemicthrough U.S.-funded research at a lab in Wuhan, China, and then participated in a coordinated government-scientific cover-up,misleading Congress to conceal that connectionand suppress the laboratory-leak explanation. Paul, a Republican, hasrepeatedly calledfor Fauci's prosecution.

In January 2025, President Joe Biden granted Fauci apreemptive pardoncovering potential federal offensesrelated to his government service since 2014. Fauci had not been charged with a crime, butcritics portrayed the pardon as evidencethat he had something to hide. Fauci has denied claims of wrongdoing and hastestified multiple times before Congress.

The Fauci conspiracy ismuch bigger than Rand Paul, though. Paul may be its most persistent congressional promoter, but it's been amplified by awider network of Republican lawmakers. Several Republican members of Congress, such asRep. Steve Scalise,Rep. James Comer and former Rep. Brad Wenstrup, among others, haveadvanced versionsof the Fauci/COVID-origin narrative.House Republicans formally investigatedthese claims for two years, while members repeatedlyaccused Fauci of suppressing the lab-leak theoryand misleading the public.

That investigation ultimately endorsed a central claim of the conspiracy narrative: the House GOP'sCOVID-19 investigation concludedthe virus most likely leaked from a Wuhan lab, that Fauci helped shape a scientific paper dismissing that theory, and that he privately testified the six feet apart" guidance sort of just appeared" - though these are the conclusions of a partisan committee, not an independent inquiry, and Fauci andDemocratic membershave disputed them.

I'm anassociate professor of sociology and criminology, and my scholarship focuses on far-right networks and digital radicalization - the exact ecosystem where these conspiracy theories have taken root and spread. My research on how these movements evolve online and intersect with political activists and extremist networks was directly relevant to tracing how COVID-origin claims moved from fringe communities into mainstream political discourse.

Fauci's decision to invoke theFifth Amendment, which he and his lawyer explained not only as a basic constitutional right but also a strategy to avoid the possibility that Paul might try to prosecute him for lying to Congress based on anything he might say, may bepolitically explosiveand provide his opponents with another talking point. But, in my assessment, the spectacle says more about what happens when conspiracy theories becomeembedded in political institutionsthan it does about the origins of COVID-19.

From uncertainty to conspiracy

COVID-19 created the conditions in which conspiracy theories flourish:enormous uncertainty, frightening consequences, rapidly changing information anddistrust of institutions.

People wanted explanations. Why did the virusappear in Wuhan? Why didrecommendations about masks change? How were vaccinesdeveloped so quickly?

These questions were legitimate. Problems emerged when those questions became connected to a predetermined conclusion: Powerful people either created the pandemic or concealed the connection to the lab in Wuhan.

A 2021 survey by the Public Religion Research Institute illustrates how widespreadone version of this thinkingwas. About 4 in 10 Americans - 39% - agreed that the coronavirus had been intentionally developed by scientists in a laboratory. AmongQAnon believers- a sprawling conspiracy theory claiming that a cabal of powerful elites, often portrayed as child-trafficking Satanists, controls government and society and that Donald Trump was secretly fighting it - the figure was dramatically higher, at 85%. The same survey found that people who embraced anti-elite and anti-expert attitudes were more likely to acceptcoronavirus conspiracy theories.

Conspiracy thinking is rarely isolated. For example, a person who comes to believe that public health officials aresecretly manipulating informationmay be morereceptive to claimsthat vaccines contain hidden dangers. Someone who distrusts pharmaceutical companies may be more receptive to claims that the pandemic was engineered for profit. Someone who believes powerful elites routinely operate in secret may be more receptive to broader conspiracy narratives such asQAnon.

Thesebeliefs can reinforce one another, creating a broader worldview in which institutions, experts and government officials are presumed to be acting deceptively.

The Fauci conspiracy

Because Fauci was highly visible during the pandemic, advising presidents and appearing on television, he quickly became associated with government efforts to control the spread of the virus.

For someRepublicans and MAGA activists, and others who distrust the government and scientific institutions, Fauci came to representlockdowns, masks, vaccines and government mandates.

Anti-vaccine activists incorporated him into broader narratives about pharmaceutical companies and public health agencies. Conspiraciststook the story further, portraying Fauci as part of a secret effort toconceal the origins of COVID-19. Extremistsconnected these claimsto older ideas about government tyranny, social control and corrupt elites.

The result was a feedback loop.

Claims were generated inonline communities, repeated bypolitical figuresand amplified bymedia personalities, who injected these talking points back into supporters' social media feeds. The repetition made the claims feelincreasingly familiar- and familiarity can bemistaken for evidence.

The lab-leak question is not the same as a conspiracy theory

Asking whether SARS-CoV-2 emerged through eitherzoonotic spillover, which is when a virus jumps from animals to people, or through a laboratory-related incident is not inherently a conspiracy theory. Scientists and governments have legitimate reasons to investigate the origins of a pandemic.

The World Health Organization's independent scientific advisory group reported in 2025 that much of theinformation needed to fully evaluatethe competing hypotheses had not been provided by China. It concluded that the available evidence suggests spillover but maintained that the laboratory-leak hypothesis could not be ruled out.

There is, however, a distinction between investigating whether a laboratory accident might have occurred and claiming that scientists created a virus and intentionally released it. That distinction is important in returning to Fauci and the claims raised at the July 29 hearing: Were lawmakers investigating the possibility of an accidental laboratory release, or were they advancing the more conspiratorial idea that scientists deliberately created and released the virus?

The Republican-led House subcommittee argued thatU.S. government-funded researchmay have contributed to the pandemic.

The investigation did not establish that the virus wasintentionally manufactured or released.

Today, the scientific question ofwhere SARS-CoV-2 originated remains unresolved. But conspiracy theories can transform the absence of evidence intoevidence of concealment.

From fringe theory to political reality

The most consequential feature of conspiracy theories may be their ability to move from one group to another.

A claim can begin in anobscure online communityandspread through social mediato become a political weapon.

The Fauci hearing demonstrates the culmination of that process. These claims havemoved into the formal machinery of government, where they are being amplified by elected officials and federal agencies.A theory's credibility can increasesimply because someone with greater institutional authority has repeated it.

That may be the most important question surrounding Fauci's hearing: What happens when conspiracy theories acquire the authority of the government?
