In what case?
In the case of Hunter Biden, yes.
You are not going to persuade me that accepting s preemptive pardon is a confession. What do exactly do they confess to?
On Dec 11 a US Attorney in the US District Court in DC arguing for the Government said, citing a SCOTUS decision, accepting a pardon is a confession of guilt.
From Burdick v US
"A pardon is an act of grace, proceeding from the power entrusted with the execution of the laws, which exempts the individual on whom it is bestowed from the punishment the law inflicts for a crime he has committed."
But if you don't want it to apply to the Bidens or others, that's up to you.
