The American legal system will be unable and/or unwilling to deal with it. Best chance is to send HIM to El Salvador if he ever relinquishes the office.
The American legal system, fucked as it already was, absolutely can handle this, or could. Was. Even I have fond memories of the U.S. Marshals banging at my door, wearing obviously baggy shirts. That shit was handled by the court.
The reason why it isn’t working is someone is actively breaking it
