Needs to be stated that all those who accepted pardons now can not plead the 5th in any hearing. So, when investigations continue and ramp up on these same individuals they have to answer every question.
Also, they are federally pardoned, it does not make them immune from state and local prosecutions ala New York v Trump. So, someone like Fauci can still have chargers brought against him.
Are you contradicting yourself? Your constitutional protections are not just for federal prosecution.
