It's behind a paywall but per the Financial Times, don't hold your breath on the WHO getting anything done in China regarding their super duper deep investigation on the origins of SARS-Covid-19, unless you call getting things done pretty much sitting on their ass in Beijing and being spoon fed the story by the CCP.
At this point, it's probably too late.
My personal opinion still says that this was gain of function research that escaped the bottle. My only question now is this the research that Fauci was helping to fund?
