Anthony Fauci, former director of NIAID and prominent medical advisor during the COVID-19 pandemic, appeared before a Senate Homeland Security and Governmental Affairs Committee hearing on July 29, 2026. The big picture: Fauci invoked his Fifth Amendment right against self-incrimination and declined to answer 15 questions posed by Republican Senator Rand Paul. Fauci accused Senator Paul of an “unhinged” campaign to see him imprisoned, citing years of public criticism and repeated calls for his prosecution. Fauci’s legal counsel described Paul’s actions as an “obsessive vendetta,” criticizing the hearing as retaliatory and based on false allegations. The hearing’s Democratic ranking member, Senator Gary Peters, condemned it as biased and accused the majority of trying to legitimize a predetermined conclusion.
