You're going to be really, really disappointed on this one. Stop reading Sara Carter nonsense and get into the real world.
Flynn's lawyers are running a clown show, and they're taking their defendant, who pleaded guilty, from a chance to get probation into jail.
They have the call transcripts that lay out what he did, plus he cooperated already with the prosecutors, laying out evidence of what he did. That remains admissible in court.
His whole legal defense now consists of insane conspiracy theories (Peter Strzok is out to get me!) that only make sense if the plan is to get a pardon from Trump.
The judge has not postponed his hearing because the defense has won something. They've done so because they're filing spurious motions. The judge has issued zero rulings that benefit the defense. His main public action to date was to tell Flynn that he was likely to give him a harsher punishment than was originally suggested by his plea agreement.
