Chutkan had no choice but to put the trial on hold, as Trumps appeal to the next higher court(don't remember which one), above Chutkan, once they took the case, automatically, takes the case out of her hands. She can do absolutely nothing, until the higher court rules. That is why Jack Smith appealed to the US Supreme Court, trying to jump ahead of the next higher court, so, he could keep the trial on schedule for March 4th.
He Failed
Good deal! Thanks for the clarification!
