Two senior Republican senators are calling on the Trump Justice Department to do something no administration has attempted in modern memory: challenge the legality of a presidential pardon and pursue criminal charges against the man it was designed to protect, Dr. Anthony Fauci.
Sen. Rand Paul and Sen. Ron Johnson (R-Wis.) made the case in separate appearances this week, arguing that President Joe Biden's 2024 pardon of the nation's former top pandemic official is constitutionally vulnerable and should not stand as a shield against prosecution. Their push comes as federal prosecutors have already indicted two former Fauci lieutenants, tightening the investigative circle around the man Paul has pursued for years.
The senators' argument rests on an unusual set of facts: Biden signed the pardon by autopen before leaving office, it covers a sweeping ten-year period, and it names no specific crime. Paul contends those features make it ripe for a legal challenge, and that the indictments of Fauci's former associates could produce testimony that changes the entire landscape.
Paul, a longtime Fauci critic who has accused the doctor of misleading Congress, laid out his reasoning on the Just the News, No Noise television show this week:
"I think we should challenge the pardon, because it's an extraordinary pardon. It's a pardon not for a specific crime, and it's a pardon over a 10 year period. It's the same that he got the same thing Hunter Biden got."
The comparison to Hunter Biden's pardon is deliberate. Biden's son has himself acknowledged the role of privilege in receiving his father's clemency, an admission that undercuts any pretense that the pardons were routine exercises of executive power.
Paul pressed further on the autopen question, raising Biden's cognitive fitness as a factor that could undermine the pardon's legitimacy:
"Was President Biden of sound mind? Did he understand who he was pardoning? Did he participate in it? Did he approve of each of the ones that were signed by autopen?"
Whether a court would entertain such a challenge is an open question. Presidential pardon power is broad, and no modern precedent exists for a successor administration successfully overturning one. But Paul is betting that the unusual breadth and mechanical execution of Biden's late-term pardons create an opening no previous case has tested.
Johnson was blunter. The Wisconsin senator told Just the News that Fauci deserves criminal prosecution, full stop.
"Anthony Fauci is a bad person, and he ought to be prosecuted, because I believe he did commit crimes."
Johnson said he is "pretty certain" that the research Fauci funded caused the COVID pandemic, a claim that remains hotly contested but has gained credibility as more evidence has emerged about the nature of the work conducted at the Wuhan, China laboratory.
The Trump DOJ has not publicly responded to either senator's call. But the department's willingness to pursue politically charged prosecutions is well established. The same Justice Department has brought fraud charges against the Southern Poverty Law Center and moved forward with cases against other figures who once seemed untouchable.
Paul's committee released a detailed timeline last week connecting Fauci to what the senator describes as a coordinated effort to suppress the lab-leak theory from the earliest days of the pandemic. The timeline, as Paul described it, traces a sequence of events that began in late January 2020.
Fauci was awake at 3 a.m. during that period, Paul said, emailing Dr. Robert Kadlec and falsely asserting the virus originated in animals with "nothing to do with the lab." Days later, on February 1, 2020, a group of top virologists privately told Fauci the virus appeared engineered, citing its furin cleavage site.
What happened next is what Paul calls the cover-up. Within days of that February 1 meeting, several of those same scientists published a paper declaring the virus was "not a laboratory construct." Paul alleges Fauci helped commission and edit that paper, then cited it during White House briefings as if it were independent scientific evidence against a lab leak.
Paul described the paper's language as "adamant language you rarely see in a scientific article, political type of language, PR type of language." He also alleged that one author of the paper later received an $8 million grant approved by Fauci, a detail that, if accurate, raises serious questions about whether federal research dollars were used to reward scientists who helped shape a preferred narrative.
Paul also alleged that Fauci called on old friends within the intelligence community to mislead them about the Wuhan lab's role. The senator's characterization of the network was direct: "It's a big circle, but it's all around Anthony Fauci."
Former FBI Director James Comey, another recipient of a Biden pardon, has claimed he never sought the clemency, but the pattern of last-minute pardons for politically connected figures has only deepened Republican suspicion that Biden used his final hours to obstruct future accountability.
The indictments of two former Fauci associates add weight to the senators' push. David Morens, a former senior NIAID official, has been federally indicted on charges of destroying records and acting as Fauci's intermediary. Vincent Munster, a virologist described as a foreign national working at the National Institutes of Health, has been charged in connection with importing dangerous pathogens into the country without a permit, allegedly claiming the materials were "diagnostic equipment."
Paul sees both cases as potential leverage. If Morens and Munster face serious prison time, they may have reason to cooperate, and their testimony could reach Fauci directly.
"My goodness, it would be worth it to see one or two of his lieutenants give up testimony that they would not have given up otherwise, but now that they've been indicted, might be inclined to tell the truth."
Both men were involved in research grants that proposed creating viruses with features similar to SARS-CoV-2, according to Paul's account. The question is whether prosecutors can build a chain from those grants, through the alleged cover-up, to Fauci himself.
Fauci has long denied wrongdoing and dismissed such criticisms. But denial is not the same as exoneration, and the legal walls are closing in on the people who worked closest to him.
When Biden issued the preemptive pardon in his final hours in office, Paul framed it as an admission. As Breitbart reported at the time, Paul declared that Fauci "will go down in history as the first government scientist to be preemptively pardoned for a crime." Biden also pardoned General Mark Milley, Liz Cheney, and members of the January 6 Committee in the same batch, a move House Oversight Committee Republicans criticized as shielding allies and family members from legal accountability.
Paul chairs the Senate Homeland Security and Governmental Affairs Committee, giving him broad investigative authority over the pandemic's origins. Even before the pardon, Paul had been building his case. In December 2024, he appeared on Fox News stating flatly that he could prove Fauci lied, while acknowledging a pardon might follow.
That pardon came. Now Paul wants it thrown out.
The legal path is uncertain. Courts have rarely, if ever, been asked to void a presidential pardon on grounds of vagueness or the signer's mental fitness. But the political path is clear: Republicans believe the pardon was not an act of mercy but an act of obstruction, designed to keep Fauci beyond the reach of a Justice Department that might finally ask the hard questions.
The Trump DOJ's willingness to pursue federal cases against politically prominent figures suggests this is not a fight the administration will shy away from. Whether the pardon holds or falls, the indictments of Morens and Munster ensure that the investigation continues, with or without Fauci in the defendant's chair.
A pardon is supposed to close a chapter. This one may have opened a new one, because when a president pardons someone for crimes he won't name, over a decade he won't specify, using a machine because he may not have been able to sign it himself, the document raises more questions than it answers.
