Firing "The Man" Fauci in the middle of the worse pandemic in a century would not go well for the bunkerbitch and his popularity, whether he is doing the firing or whether his "suckballs" people do the firing
Fauci has civil service protection. Only the head of of the Department of Health and Human services can fire him.
Even if he did fire him Fauci can appeal his firing as a civil servant if he was not fired for cause.
