Have you got a link to examples? I’m wondering if they weren’t also saying that China deliberately leaked the virus.
Saying “it is possible but very unlikely that the virus leaked from a Wuhan lab” is talking about the lab-leak theory. Saying “the virus was cooked up and leaked from a Wuhan lab to hurt Trump’s re-election chances” is also talking about the lab-leak theory.
