“made the jump from animals to humans”..
No credibility.
I disagree with your brother, former Harvard Virologist Dr. William Haseltine, and with his former colleague, Dr. Charles Lieber, the former Chair of Harvard University’s Chemistry and Chemical Biology Department (until he was arrested) and also a “Strategic Scientist” at Wuhan University of Technology (WUT).
Wuhan virology lab runs its routine research and production on animals, including both bats and pigs. It is rumored that when the lab has used up a batch of animals such that they are not valid subjects for further tests, then the lab sells those animals to the market.
It is very possible that there was animal to human path. It is very possible that there are two or more paths and two or more #1s. We in the US do not know.
Maybe a few in Wuhan knew. They are not talking. China might have its own form of Hillarycide.
“No credibility.”
Why not?
