Still hasn't gone far enough. The Bureau of Matters is only "looking" into his tax matters. So basically they're not even looking into if he was illegally gaining money, or if his father was illegally using his son to launder it for him. It's clear that Hunter did zero work for that money. They're just doing it so they can come out and say "All clear, nothing here! You see, Hunter paid taxes on all of that illegal income that sold out our country!".

I mean for christ sake, there's pictures and video of him doing sexual stuff with an underage family member and they're still bird boxing around.
