I mean if you ever got him into a courtroom that'd be the end of him. He can hardly speak coherently and being questioned would lead to him just have a mental breakdown probably 5 minutes in. He'd contradict himself every 5 minutes and yell/insult probably the entire prosecution and courthouse. I know his lawyers would tell him to stay quiet, but there's no way he'd ever do that. In fact, I'm sure this dumb motherfucker would try to reach a settlement in his own fucking impeachment trial. I imagine that would turn most Republicans that have at least some shred of decency left in them. There's no hope in convincing any of his base, they think he's the literal second coming of christ and everything he says in the present day is gospel even if it directly contradicts what he said just days or hours earlier.
