There must be plenty of things that Trump can do. One might be regarding that gag order. At sentencing, he could require that his actual accuser on the indictment get on the stand and show damage and proof that it was him (Trump) that did it. Call it cross examination by Trump. Since Trump had been gagged, he couldn't ask the question. So, he could file paperwork "Fraud on the Court," and if Merchan doesn't give him (Trump) his chance to cross examine his accuser, "Fraud on the court by the court." Legal terms. This could at least extend his sentencing past election time.
