Dr. Anthony Fauci testifies before a U.S. Senate Homeland Security and Governmental Affairs Committee panel as lawmakers question what he knew and how decisions were made during the COVID-19 pandemic’s early stages. The appearance comes nearly six years after the pandemic began and is linked to an investigation led by committee Chairman Sen. Rand Paul into the origins of COVID-19 and related government actions.

Ahead of the testimony, CBS reports that days earlier Paul released a set of Fauci diary entries. The documents describe Fauci’s relationship with former President Donald Trump and provide his account of elements of the pandemic response. NBC reports that senators are expected to use the hearing to press Fauci on both information he had at the time and what he did not, along with how developments were assessed as the outbreak unfolded.

No single outlet describes the specific questions or expected outcomes in detail, but both accounts frame the hearing as a formal opportunity for the committee to seek clarification on early pandemic handling and the search for the virus’s origins.
