How did you see it? The kangaroo court prohibited TV cameras in court, IIRC.
See my comment #24. Regarding Trump sleeping, possibly someone took cell ohone pictures, or mini camera photo.
I did not see the Judge issuing instructions, I saw a commentor describing the issues and instructions.
See my comment #24. Also regarding possible napping in court, I imagine it is possible to sneak a cell phone shot or video, or a very small camera into the court. Regarding the Judges instructions, what I saw was an explanation on a program discussing the kinds of instructions the Judge would or did give to jurors.
