It seems that Fauci's emails have been made public (because he works for us and his official emails are public record), and he's on the defensive.
He says that science evolves as we learn more about things, and that science is never settled.
The question becomes when he knew something, and when his advise changed. And, just exactly what the scientific community knew about the virus and how they skewed the message to affect public behavior.
Why anyone listens to Tony Faucci anymore is a huge question of Stockholm Syndrome.
