Facts: Trump stole classified documents, stored them in unsecured locations (not even behind a locked door), lied about having them to FBI, Archives, and lawyers. He bragged about having them to others and even showed them to people without clearance. He had them moved around hoping the FBI would not find them.
Republicans had Congress, Senate, Justice Dept., Supreme Court, and Executive during the Trump Admin and did not prosecute Hillary (or Biden or Obama) for anything. Yet "Lock her up" has been the cry ever since 2016. Why didn't they prosecute? Either they could not find charges that would stick or the republicans are completely inept. It certainly is not some moral standard. The "deep state" argument is pretty pathetic given the amount of time republicans have been in power over past 20+ years.
BTW: Hunter Biden is in a lot of hot water now. The Justice system works, just slowly. And Trump is going to lose this case because he is a traitor to the United States.
