Senate report and former intelligence chief support lab leak theory for COVID origins.

A 302-page Senate report obtained by Axios suggests that the coronavirus pandemic may have originated from a laboratory accident due to biosafety issues in Wuhan, China. The report evaluates the two leading theories, transfer from wild animals or an accident at a Chinese government lab, and concludes the latter is stronger. The report's case for a lab accident being the cause relies on several lines of evidence, including the absence of naturally occurring viruses with the same composition of the coronavirus and evidence that the virus was circulating in Wuhan before the first known cases connected to the wet market were reported.
