Not guilty of what? Everything? Money laundering, tax evasion, insider trading, wire fraud, cheating on his wife?
Using his office to enrich himself and his friends? He may be stupid and somewhat clueless but innocent? No, he's not innocent.

There is no Trump Tower in Russia. They don't like him. He's just a useful tool.
Lock him up.
