The genuine reason is because it was a active investigation. The FBI has been looking into this for fuckin yearrsssss. Biden literally couldn’t do shit until the DOJ stopped their investigation. The problem Trump ran into was stopping the investigation. Thus the DOJ then was free to release whatever was needed. Although congress did push their hand to release faster. Either way, Biden didn’t release it because A) he didn’t promise to not really campaigned on it and B) literally couldn’t.
