Anthony Fauci invoked his Fifth Amendment rights and refused to answer questions during a U.S. Senate hearing on Covid-19 origins on July 29, 2026 [1].
The refusal marks a significant escalation in the long-standing conflict between the former Director of the National Institute of Allergy and Infectious Diseases and Republican lawmakers over the pandemic's beginnings. By pleading the Fifth, Fauci avoided providing testimony that could potentially be used against him in a legal setting.
The hearing took place before the Senate Committee on Health, Education, Labor, and Pensions in Washington, D.C. [1]. During the proceedings, Fauci declined to answer questions from Sen. Rand Paul (R-Ky.), and said, "I am invoking my Fifth Amendment rights and will not answer any of Senator Paul's questions" [2].
Fauci said he feared that Republicans would try to "trip him up" and use his testimony to prosecute him for perjury [3]. He said the line of questioning regarding the origins of the virus was an "obsession" [3].
Throughout the session, Fauci invoked the Fifth Amendment more than 100 times [1]. This repeated refusal created a stalemate in the committee's attempt to gather information on how the virus first emerged.
Sen. Paul responded to the refusal and said, "Your obsession with the origins of the virus is unhinged" [4]. The exchange highlighted the deep partisan divide regarding the oversight of public health officials and the transparency of government research during the pandemic.
“"I am invoking my Fifth Amendment rights and will not answer any of Senator Paul's questions."”
The decision by a former top public health official to plead the Fifth Amendment in a congressional hearing is rare and suggests a high level of legal risk. It indicates that the dispute over Covid-19 origins has moved beyond political disagreement and into the realm of potential criminal liability for perjury, effectively halting the Senate committee's ability to extract new admissions from Fauci.
