This is all a big Kabuki theatre presentation designed to (a) find no actionable misconduct on the part of Biden or his senior advisors (one or more lower-level employees may have to take one for the team), and (b) to innoculate any subsequent prosecution of Trump for the Mar-a-Lago documents from accusations of political subterfuge because, after all, the DOJ went after Biden as well.
So, be prepared for some breathless reporting from the MSM - keep in mind, it's a subterfuge - followed by some tense moments of "investigation" by FBI and DOJ, followed ultimately by exoneration for Biden and his senior staff, and maybe one little scapegoat who pleads guilty, does a few months in Club Fed, and then mysteriously gets picked up by some Chinese-funded think tank for a lifetime appointment with sinecure.
