He can speak on politics, on policies he wants to run on, even talk about the other candidates, like an other candidate. This is a legal issue, so he is not allowed to interfere, intimidate or rouse out of court actions by his cult. Feel free to write a brief for the court or whatever appeals court. You are talking to the wrong guy. I approve of him not being able to threaten or intimidate the court members or witnesses.
How do you feel about his lawyer in that state, used to help attempt to overturn the vote, pleading guilty to his part in the felony conspiracy, trump was involved and charge with. I understand he will be testifying and producing documents for the prosecution, testifying without 5th amendment proctection, as he has already pleaded guilty to the charge. I guess (as a lawyer) he knew the evidence, and just didn't want to go to jail for the team trump, so decided to come clean.
