Dr. Anthony Fauci invoked his Fifth Amendment right against self-incrimination and declined to answer questions during a Senate hearing on Wednesday [1].
The refusal to testify marks a significant escalation in the ongoing investigation into the origins of the COVID-19 pandemic. Because the hearing followed the public release of pages from Fauci's private diary, the move suggests a heightened legal risk for the former official.
Republican senators, led by Sen. Rand Paul (R-KY), were probing the pandemic's origins when Fauci stopped answering questions. The committee had recently released excerpts from the doctor's private diary to support their line of questioning [2].
"I am invoking my Fifth Amendment right to avoid self-incrimination," Fauci said [2].
Reports on the timing of the invocation vary. Some accounts indicate Fauci invoked the right just minutes into the hearing, while other reports state he repeatedly invoked the amendment throughout the proceedings [3, 4].
Fauci did not maintain a purely legal tone throughout the session. During the exchange with the committee, he said, "Sen. Rand Paul is unhinged" [5].
Fauci previously served as the director of the National Institute of Allergy and Infectious Diseases. The hearing took place on Capitol Hill in Washington, D.C., on July 29, 2026 [1, 2].
“"I am invoking my Fifth Amendment right to avoid self-incrimination."”
The invocation of the Fifth Amendment by a high-profile former public health official during a congressional hearing is rare and typically signals that the witness believes their testimony could be used against them in a criminal proceeding. By linking this action to the release of private diary entries, the situation suggests that the Senate committee may have uncovered specific documentation that creates legal jeopardy for Fauci regarding the early handling or reporting of the COVID-19 pandemic.
