There is no constitutional or legal mechanism to reverse presidential pardons, so the GOP investigation into the use of the autopen will not result in them being invalidated.

“Since the pardons were accepted by the subject, there is no mechanism to reverse them. So I know this gets a lot of people hot and bothered and I respect what's the investigation, but I don't think it's going to go anywhere.”

The GOP investigation into the autopen scandal is a necessary step to potentially hold the Biden administration accountable for potentially unauthorized executive actions.

“The Republican party has released their investigation into the autopen scandal and they are formally requesting the DOJ void or at least investigate.”
