Sen. Ted Cruz wants Dr. Anthony Fauci behind bars, and after a combative Senate hearing in which the former NIH director refused to answer more than 100 questions, the Texas Republican may not be alone in that view.

Cruz labeled Fauci "the most damaging bureaucrat in American history" and demanded criminal prosecution, as Fox News reported. The remarks came on the heels of Fauci's July 29, 2026, appearance before the Senate Homeland Security and Governmental Affairs Committee, where the once-ubiquitous face of America's pandemic response sat stone-faced and repeated the same phrase over and over again.

"Under the advice of my attorneys, I will invoke my right under the Fifth Amendment," Fauci told the committee, as National Review's Jim Geraghty noted, a line he delivered dozens upon dozens of times throughout the proceedings.

A hearing that answered nothing

Committee Chairman Sen. Rand Paul, the Kentucky Republican who has clashed with Fauci for years over gain-of-function research and pandemic policy, subpoenaed the former NIAID director to testify about his handling of COVID-19. Just The News reported that the questioning centered on gain-of-function research related to the origins of the pandemic, a subject Fauci has long been accused of misleading Congress about.

Fauci did not cooperate. He invoked his Fifth Amendment right against self-incrimination and declined to answer the committee's questions. AP News reported that the number exceeded 100 refusals. The hearing quickly became a standoff between a senator who has spent years building a case and a witness who refused to engage.

Fauci, for his part, cast the entire proceeding as a political vendetta. He told the committee:

"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, behind bars."

Paul offered a different framing entirely. The chairman opened the hearing with a declaration that left no ambiguity about his intentions:

"Today will be the capstone to Anthony Fauci's 40 years of abuse of power at NIH."

The pardon problem

Fauci's legal posture is unusual. President Biden issued him a pardon before leaving office in early 2025. But that pardon has limits that matter enormously in this context.

National Review reported that Biden's pardon covers the period from January 1, 2014, through January 19, 2025. It does not cover perjury, contempt of Congress, or any criminal conduct occurring after that cutoff date. That distinction is critical: anything Fauci said or refused to say at the July 29, 2026, hearing falls outside the pardon's protective window.

Republicans on the committee raised pointed questions about whether the pardon affects Fauci's eligibility to invoke the Fifth Amendment at all. The legal theory is straightforward. The Fifth Amendment protects against compelled self-incrimination. If a pardon removes the possibility of criminal liability for past conduct, the argument goes, a witness cannot claim the privilege for questions about that pardoned conduct because there is no remaining jeopardy to incriminate against.

Fauci's attorneys apparently calculated that the risk of new charges, including contempt or perjury, justified blanket invocation. Whether that calculation holds up is now a question for the committee and, potentially, the Justice Department. The tension between a pardon designed to shield Fauci and a hearing designed to extract answers has created a legal knot that neither side seems eager to untangle quietly. When federal prosecutors have shown willingness to charge government officials for conduct related to pandemic-era abuses, Fauci's legal team has reason to take the threat seriously.

Contempt vote looms

Paul announced that the committee will vote next week on whether to hold Fauci in contempt of Congress for his refusal to testify. Newsmax reported that Paul warned Fauci he may still face repercussions for obstructing a congressional investigation.

A contempt finding by the committee would be referred to the full Senate and then potentially to the Justice Department for prosecution. Contempt of Congress is a federal misdemeanor carrying up to one year in prison and a fine of up to $100,000. For a man who spent decades wielding enormous power over American public health policy, the prospect of a criminal referral represents a dramatic reversal of fortune.

Health Secretary Robert F. Kennedy Jr. added fuel to the fire. Newsmax reported that Kennedy stated he believed Fauci might lie before the committee, opening him to perjury prosecution despite his presidential pardon. Perjury before Congress is a felony carrying up to five years in prison. Kennedy's public statement suggests the administration views Fauci's legal exposure as real, not theoretical.

Cruz turns up the heat

Cruz's demand for jail time goes beyond the contempt question. The Texas senator has long argued that Fauci misled Congress about the National Institutes of Health's funding of gain-of-function research at the Wuhan Institute of Virology. Cruz's characterization of Fauci as the "most damaging bureaucrat" in American history reflects a broader conservative argument: that Fauci's pandemic policies caused incalculable harm to the economy, to children's education, and to public trust in institutions.

The demand also reflects a growing frustration among Republican lawmakers that Biden's pardon was designed to place Fauci beyond accountability. Cruz and his allies appear determined to test the limits of that shield. The federal government has demonstrated in other high-profile cases that it will pursue accountability even when the targets are powerful figures who believed themselves untouchable.

Florida opens its own investigation

The Senate hearing is not the only front. Just The News reported that Florida's attorney general launched an investigation into Fauci following what the office described as his "lack of candor" at the hearing. The state-level probe adds another layer of legal exposure for Fauci, who now faces potential consequences from both federal and state authorities.

The Florida investigation signals that red-state attorneys general may be willing to pursue Fauci independently of whatever Congress decides. State-level investigations operate on different timelines and under different legal standards than congressional proceedings, and a presidential pardon does not cover state criminal charges.

What comes next

The committee's contempt vote next week will be the immediate flashpoint. If the Republican-led panel votes to hold Fauci in contempt, the referral would move to the full Senate and then to the Department of Justice under Attorney General appointees of President Trump.

Fauci's legal team will almost certainly challenge any contempt finding, likely arguing that the Fifth Amendment privilege was properly invoked regardless of the pardon's scope. That argument will force courts to address a question with limited precedent: whether a pardoned witness can invoke the privilege against self-incrimination for conduct covered by the pardon while simultaneously facing potential new charges for the act of refusing to testify.

Investigators will need to determine whether Fauci's prior congressional testimony contained material falsehoods that fall outside the pardon's coverage. Authorities have not publicly confirmed whether any specific statements from earlier hearings have been referred for perjury review. The committee has also not disclosed what evidence, if any, it has gathered that might contradict Fauci's previous claims about gain-of-function research funding.

For years, Fauci operated as one of the most powerful unelected officials in Washington, shaping policies that touched every American household. Now the man who once stood at the White House podium telling the country what to do cannot bring himself to answer a single question from the people's elected representatives. Whether that silence protects him or condemns him may be the most consequential accountability question of the post-pandemic era.
