The judge ruled on a defense motion, something he is expected to do. If Trump loses and if his attorneys appeal then they might use the ruling as part of their grounds for the appeal but until then they have to suck it up and soldier on.
I don’t see why Trump’s lawyers haven’t asked for a mistrial, on the basis that the judge (maliciously?) released information to the public that he later admitted he shouldn’t have released. He just said, “My bad,” and put it back under seal.
And as to malicious intent, in his statement along with release of the information, the judge stated something to the effect of, “My integrity in not recusing myself has been brought into question...”
If this isn’t the first motion in the Nov 28 trial, I will not understand why not.
