New evidence points to Chinese lab leaks as possible origin of COVID-19

A Senate report argues there may have been two separate lab leaks at Chinese facilities conducting risky "gain of function" research that could have unleashed the COVID-19 pandemic.
The report concludes millions of lives could have been saved if not for an alleged "coverup" by China during initial outbreaks as early as July 2019.
The theory is based in part on the timing of a Feb. 2020 patent application for a COVID-19 vaccine by a now-deceased Chinese military scientist.
A separate Senate report says evidence points more strongly to an accident at a Wuhan lab rather than spread from wild animals.
Lack of Chinese cooperation has hampered investigations into how the virus that causes COVID-19 first emerged in Wuhan.
