It's not just his opinion, the NIH themselves admitted it [1] and the lab succeeded in making the coronavirus far more virulent:

> EcoHealth and its Wuhan partner constructed novel chimeric SARS-related coronaviruses — artificial, lab-generated viruses that do not have counterparts circulating in nature — that exhibited 10,000 times enhanced viral load and two to four times enhanced pathogenicity in infection studies in mice engineered to display human receptors on their cells (‘humanized mice’).”

It's equally if not more dangerous that the public has been deceived for so long about the true origin of the virus, because it's further ruined trust in the media, government and big tech by making this event highly politicised just because a few individuals in the US government wanted to hide their own crimes.
