A pair of Republican senators on Wednesday night declared the U.S. Senate had unanimously passed their bill requiring the Biden administration to declassify intelligence related to the origins of COVID-19.

The bill, known as the COVID-19 Origin Act of 2023, specifically aims to investigate the possibility that the SARS-CoV-2 virus, which causes COVID-19, leaked from a lab in Wuhan, China.

Republican Sens. Mike Braun and Josh Hawley reintroduced the bill on Monday after the Department of Energy (DOE) provided a classified intelligence report to the White House and certain members of Congress, which concluded that the COVID-19 pandemic most likely arose from a lab leak. The FBI had previously come to a similar conclusion.

Sen. Sherrod Brown (D-Ohio) made a request for unanimous consent of the bill, which was granted ā€œwithout objection.ā€ Unanimous consent enables a bill to pass without a recorded vote.
