If you only attempt to prosecute the current executive branch, you will end up in a worse position over time. Corporations that participated in the open corruption by donating to his swearing in must be held accountable, criminally. The senators and congressmen who supported his obviously unconstitutional policies must be removed from office at the very least. The judges at all levels who very obviously ignored the constitution in pursuit of a fascist agenda with i’m sure a large quantity of kick-backs have to be disbarred.

Obviously this would require a complete overhaul of the existing structure and so has absolutely no chance of happening, but in reality, it’s the only “lawful” way to stop the continuous slide to right and perhaps allow justice to prevail for the next few decades.
