Dr. Anthony Fauci invoked his Fifth Amendment right against self-incrimination during a closed-door deposition with the House Select Subcommittee on the Coronavirus Pandemic, a move that has intensified Republican demands to hold him legally accountable for his handling of the COVID-19 crisis. The development landed just weeks after President Biden issued Fauci a sweeping preemptive pardon on his final day in office.
Fauci's decision to plead the Fifth stunned several committee members who had expected him to answer questions about gain-of-function research, the origins of COVID-19, and his role in shaping federal pandemic policy. The former director of the National Institute of Allergy and Infectious Diseases had previously testified before Congress on multiple occasions, making his refusal to answer questions under oath a sharp departure from his earlier posture.
The deposition took place as part of an ongoing congressional investigation into the federal government's pandemic response. Fauci appeared before the subcommittee but declined to answer a range of questions, citing his Fifth Amendment protections. Committee members said he invoked the right repeatedly across multiple lines of questioning.
Rep. Marjorie Taylor Greene, R-Ga., who participated in the deposition, told Fox News she was not surprised by Fauci's approach. Greene said Fauci "lawyered up" and chose silence over transparency. She framed the Fifth Amendment invocation as an admission that Fauci understood the legal jeopardy he could face, pardon or not.
Rep. Rich McCormick, R-Ga., a physician and member of the subcommittee, told Fox News that Fauci's refusal to testify openly only deepened suspicion about what the former NIAID chief may be concealing. McCormick said the committee would not relent.
Biden's preemptive pardon, issued January 20, covered a broad range of potential federal offenses. The pardon was widely viewed as an attempt to shield Fauci from criminal prosecution under the incoming Trump administration. Republicans had signaled for months that they intended to pursue accountability measures against Fauci once Trump returned to office.
But the pardon's scope has limits that lawmakers say leave Fauci exposed. A presidential pardon covers only federal criminal liability. It does not protect against civil lawsuits, state-level charges, or congressional subpoena power. Nor does it relieve Fauci of the obligation to testify truthfully if he chooses to answer questions rather than invoke the Fifth.
Legal observers have noted that invoking the Fifth Amendment after receiving a pardon creates an unusual dynamic. In many legal contexts, a pardon removes the basis for self-incrimination claims because the recipient can no longer face criminal prosecution for the pardoned conduct. Courts have at times compelled pardoned individuals to testify on that theory. Whether Fauci's Fifth Amendment invocation can withstand a legal challenge remains an open question.
The strongest reaction came from lawmakers who pledged to pursue Fauci through civil and congressional channels regardless of the pardon. McCormick vowed to haul Fauci into court "every day" if necessary, framing the effort as essential to uncovering the full truth about pandemic decision-making.
"We will haul him into court every day if we have to."
McCormick's pledge reflects a broader Republican strategy that treats the pardon not as a dead end but as a reason to press harder through non-criminal avenues. Subcommittee Chairman Brad Wenstrup, R-Ohio, who led the pandemic investigation through the previous Congress, had already built a substantial record of testimony and documents. The new Congress appears ready to build on that foundation.
Greene echoed the combative tone, saying Fauci's silence confirmed what many conservatives have long believed: that the former public health official has something to hide about the origins of COVID-19 and the federal government's relationship with the Wuhan Institute of Virology.
At the heart of the congressional investigation sits the question of whether U.S. taxpayer dollars, routed through the National Institutes of Health, funded gain-of-function research at the Wuhan Institute of Virology. Gain-of-function research involves modifying pathogens to make them more transmissible or more dangerous, typically to study pandemic preparedness.
Fauci has previously denied that NIH funded gain-of-function research in Wuhan, a claim that has been challenged by documents, by other scientists, and by findings from the subcommittee's own investigation. Internal NIH communications obtained by the committee appeared to show that senior officials, including Fauci, were aware of research activities in Wuhan that met common definitions of gain-of-function work.
The subcommittee's earlier findings also raised questions about whether Fauci and other officials worked to suppress the lab-leak hypothesis in the early months of the pandemic. Emails released during prior rounds of investigation showed that Fauci was privately told by top virologists in early 2020 that the virus looked potentially engineered, even as he publicly promoted a natural-origin theory.
Fauci's invocation of the Fifth sets up a potential constitutional confrontation. If the subcommittee believes the pardon eliminates Fauci's basis for claiming self-incrimination, it could seek a court order compelling him to testify. Fauci's legal team would then need to argue that the pardon does not cover all potential criminal exposure, or that other legal risks justify continued silence.
That fight could take months to resolve. Federal courts have not produced a single, clear rule governing Fifth Amendment claims by pardoned individuals. The outcome would likely depend on how broadly the Biden pardon was drafted and whether any unpardoned conduct remains at issue.
Congressional contempt is another tool available to lawmakers. If Fauci refuses a valid subpoena and a court rejects his Fifth Amendment claim, the House could hold him in contempt. Under current law, contempt of Congress can be referred to the Department of Justice for prosecution, a path that would carry real weight under an administration already hostile to Fauci.
For Republicans, Fauci has become a symbol of unchecked bureaucratic power during the pandemic. School closures, vaccine mandates, mask requirements, and business shutdowns all trace back, in the conservative narrative, to guidance that Fauci championed. Holding him accountable is not merely a policy goal for many GOP lawmakers; it is a promise made to voters during the 2024 campaign cycle.
Democrats have largely defended Fauci as a dedicated public servant who navigated an unprecedented crisis. They have characterized Republican investigations as politically motivated and warned that aggressive pursuit of former officials could chill future public health responses.
That argument has gained little traction with the Republican base or with families who say pandemic policies destroyed livelihoods, harmed children's development, and eroded trust in public institutions. The Fifth Amendment invocation is unlikely to soften that anger.
The subcommittee has not announced its next procedural step. Lawmakers could issue new subpoenas, seek a contempt referral, or pursue civil litigation to compel testimony. The Trump administration's Department of Justice could also open its own investigation into Fauci's conduct, though the pardon would block federal criminal charges for covered offenses.
Investigators will need to determine whether the pardon's language leaves any gaps that could expose Fauci to federal liability. They will also need to assess whether state attorneys general might pursue parallel inquiries, a path that the presidential pardon cannot obstruct.
Fauci's legal team has not publicly commented on the strategy behind the Fifth Amendment invocation or on how they interpret the pardon's scope. Whether Fauci will continue to invoke the Fifth in future proceedings, or whether a court will strip him of that option, remains unresolved.
A pardon was supposed to close the book. Instead, it may have opened a chapter that Fauci and his allies never wanted written.
