This article in the Post about how the State Department was warning that a Coronavirus could escape from the Wuhan Lab’s insufficient containment system seems credible.
“Two years before the novel coronavirus pandemic upended the world, U.S. Embassy officials visited a Chinese research facility in the city of Wuhan several times and sent two official warnings back to Washington about inadequate safety at the lab, which was conducting risky studies on coronaviruses from bats. The cables have fueled discussions inside the U.S. government about whether this or another Wuhan lab was the source of the virus — even though conclusive proof has yet to emerge.”
To be clear: he’s not saying it was “manufactured” in the lab, or deliberately released. Just that it seems more likely to have infected someone at/or otherwise escaped from it.
