He has no integrity as far as I am concerned. He had to have known what he was getting into. If not then he was naive. Fauci is an example of integrity. Yes Fauci told the "noble lie" that masks were not necessary early on but that was to ensure that front line health professionals could get appropriate supplies.
Hahn's only motivation is ego and hubris. He likely will get a position where he rakes in the $$ supported by rich benefactors but I am not impressed.
I have met him on several occasions and was favorably impressed but when he was needed most he failed.
Fauci’s lying about masks up front was an unmitigated disaster, as we are now seeing. Terrible, terrible idea
