.............what he also can do is ORDER Mueller to come into his court and be sworn in and take the witness stand and answer questions put to him by the judge and the Defense team.
Then, If Mueller lies, he’s in deep doo!
If he won’t answer a question, the judge can order him to or find him in contempt and he could go straight to jail from the witness stand. I’ve seen it happen and in relatively trivial, civil, matters.
You are absolutely right! Screw mule face!!
