Not only will there be no punitive action taken by this admin, but I fully expect Trump to extend the current flurry of lame-duck pardons to most if not all members of his administration, for any and all actions they may have taken, before his term is out.
I hope I’m wrong, but in his 5 years as President he has yet to display any hint of restraint or ethical compass, so I would be very surprised if this doesn’t happen.
EDIT: “to punitive action” => “no punitive action”
