At a Senate Homeland Security and Governmental Affairs hearing, scientists and lawmakers debated the origins of COVID-19, with opinions divided between a natural spillover and a lab leak from the Wuhan Institute of Virology. Dr. Anthony Fauci reiterated his belief that a natural origin is more likely, despite acknowledging the need to keep an open mind. Dr. Robert Garry, aligned with Fauci, argued for a natural spillover, while Dr. Richard Ebright and Dr. Steven Quay strongly supported the lab leak theory, citing lack of evidence for natural origins. The hearing highlighted ongoing frustration over perceived cover-ups by both Chinese and U.S. authorities. Senator Rand Paul emphasized the need for transparency and criticized government scientists for allegedly concealing information that supports the lab leak theory.
