what trump should do is a lawsuit naming those individuals and the info uncovered...the judge can stop him from talking he can’t stop a sepret lawsuit from being filed. even if it’s a looser of a law suit it would have the effect of going around the judges order and there is nothing the judge can do because the documents filed in the suit are public documents. he can even do it in a different court where that judge has no control.
Maybe that’s why the legal challenge to change the venue was filed in the first place — to open up another avenue to circumvent this gag order.
