At this point I’d serve a Notice of Deposition on the judge and a subpoena duces tecum for his corresponcence, email, and phone records - court and personal. Time to up the ante. See how far the federal judiciary is prepared to go to protect a rogue judge.
That would be a great and appropriate move! It’s a must.
But who would do it? Barr? I think who would do such a maneuver is the fly in the ointment.
