Anthony Fauci, the former chief White House medical adviser and long-time director of the National Institute of Allergy and Infectious Diseases, is due to testify before the Senate Homeland Security Committee after his pandemic-era diary entries were released by the panel's Republican chair, Rand Paul. The hearing is expected to reopen scrutiny of COVID-19's origins and claims that health officials may have misled Congress during the pandemic response, making it a significant moment in the ongoing political reckoning over America's handling of the outbreak.

The diaries' release has itself become a point of contention, with critics arguing that major news outlets have focused coverage on political attacks tied to former President Donald Trump rather than scrutinising Fauci's own recorded statements and recommendations on measures such as lockdowns and mask-wearing. No further details of the diary contents or a confirmed hearing date have yet been reported.
