Dr. Anthony Fauci invoked his Fifth Amendment right and declined to answer 15 questions [1] during a Senate COVID-19 hearing on July 29, 2026 [2].
The refusal to testify marks a significant escalation in the long-standing conflict between the former top U.S. infectious disease expert and congressional critics over the pandemic's origins and response.
The hearing, held in Washington, D.C., was chaired by Sen. Rand Paul (R-KY). During the proceedings, Fauci refused to answer a series of questions, saying, "I will not answer any of these questions" [1].
Fauci said the line of inquiry could expose him to criminal liability. He said the efforts to question him were an "unhinged" campaign to see him imprisoned [2].
Sen. Paul challenged the legality of the move during the hearing. "You cannot plead the Fifth, and a pardon from former President Biden would not protect you," Paul said [1].
The confrontation centered on the specific nature of the questions posed by Paul, which Fauci characterized as part of a targeted effort to secure his imprisonment [2]. The refusal to answer 15 specific questions [1] brings the legislative inquiry to a standstill regarding those particular lines of evidence.
“"I will not answer any of these questions."”
The invocation of the Fifth Amendment by a former high-ranking public health official suggests a transition from political disagreement to potential legal jeopardy. By citing criminal liability, Fauci indicates that the testimony requested by the Senate committee may overlap with active or anticipated judicial proceedings, effectively shielding his statements from being used in a court of law.
