Needs splainin'. They are free to do more splainin; Lots more. Particularly the government.
If he waived statutue of limitations, but owed money from those years and the government did not charge or seek recovery that will not be pretty. There is a narrative in the press that the statute of limitations barred action there. That does not mean they are right. Getting the right story has been difficult. The government needs to be prepared to splain that to the committee though.
It is also possible that Hunter did not want to plead. But they sweetened the pot for him. Don't know. MORE TO COME.
Conflict between the investigators and the prosecutors, whoever heard of such a thing. We don’t even know if these claims are factual. The investigation side, and especially the paper pushers like this guy, are often not privy to the target’s counter claims/arguments.
Anyways, what I can say is that the backend of what they looked into with Hunter Biden doesn’t seem like they left rocks unturned and that’s your major claim. That Weiss and the FBI/IRS missed some accounts or income. Not based on what these guys say.
