I'm sorry that your brain is so clouded with CNN or MSDNCIA mishegoss... The FBI is part of what's more accurately known as 'The Real State', than being part of any given Administration. It was Obama's FBI Director, James Comey - who initially failed to adequately investigate, and then seek proper prosecution of Hillary Clinton, over her Illegal handling of classified documents. And as we've seen pretty consistently, Trump wasn't particularly competent, or capable of controlling even his own administration. A good example, was his failed attempt to exit Syria. The Special Intelligence asset assigned to Syria by the State Department just lied to him about the number troops illegally occupying Syria.
Hillary Clinton committed the exact same crime, and got away with it, because she's an "Intelligence Community" insider - and has been, since at least her days at the Rose Law Firm in Arkansas. Her husband (also a CIA asset), https://covertactionmagazine.com/2022/01/03/there-is-absolutely-no-reason-in-the-world-to-believe-that-bill-clinton-is-a-cia-asset-except-for-all-the-evidence/
had his former National Security Advisor (Sandy Berger) steal some fairly damning classified documents from the National Records, and then allegedly destroy them. Berger got probation. Now, like Epstein, he is dead, and the classified incriminating documents are no longer available to the People of the United States of America, for any purpose - allegedly.
Barack Obama just went ahead, and gave his own cousin, Dick Cheney, and George W, and the rest of that Regime, 'a pass (but not a public pardon) for Warcrimes, Crimes Against Humanity, and Torture. Julian Assange is currently in Belmarsh Prison, awaiting extradition - for exposing those crimes, as a Journalist, while the criminals walk free.
Sadly, Joe Biden had decided to cross a Rubicon that no other President has been willing to cross up-to-now - in prosecuting a predecessor in the Office. And despite the profligate criminality of every US President since FDR - this is what he chose to go after ... A crime of which he himself is guilty, to a far greater extent.
