Dr. Anthony Fauci invoked his Fifth Amendment right and declined to answer questions about the origins of COVID-19 during a Senate hearing Wednesday [1].

The proceedings mark a renewed effort by Republican lawmakers to secure definitive answers on the pandemic's start, while Democrats argue the process is politically motivated.

The hearing took place before the Senate Homeland Security and Governmental Affairs Committee in Washington, D.C. [2]. The committee was chaired by Sen. Rand Paul (R-KY), who sought to question Fauci on his handling of the pandemic and the specific origins of the virus [3].

During the testimony, Dr. Fauci declined to answer several queries. “I invoke my Fifth Amendment right and will not answer that question,” Fauci said [4]. Reports indicate that Fauci invoked this right dozens of times throughout the session [5].

Sen. Gary Peters (D-Mich.) delivered an opening statement that criticized the leadership of the committee. “The GOP chair is relitigating the past,” Peters said [6]. He argued that the hearing was an unnecessary exercise in revisiting previous actions rather than pursuing new, actionable information [7].

Sen. Paul maintained that the inquiry was necessary for public accountability. “We need to get to the truth about the virus’s origins,” Paul said [8].

The session on July 29, 2026 [1], highlighted the deep partisan divide over the investigation into the pandemic. While the GOP chair focused on potential lapses in oversight and the possibility of a laboratory leak, the Democratic minority viewed the hearing as an attempt to score political points by revisiting settled or inconclusive debates [3], [7].

“The GOP chair is relitigating the past,” Sen. Gary Peters said.

The use of the Fifth Amendment by a former high-ranking public health official during a congressional hearing signals a significant legal escalation. It suggests that the witness perceives a legal risk in providing testimony, which effectively halts the committee's ability to gather direct evidence through this specific channel and deepens the political impasse regarding the origins of COVID-19.
