Also, as far as I've been informed, Dr. Fauci is an internationally recognized expert in infectious diseases, of the kind that the US would, under normal circumstances, celebrate as "one of their own".
Interesting that a very non-expert disagreeing with a very expert results in the very non-expert throwing the very expert under the bus. Politics can only defeat Reality in the very short term.
