Not sure when the judge will decide. Could be next week sometime. Ill never have certainty with anything in DC as far as the courts are concerned but the DOJ gives sound reasoning why the case should be dropped based on the recent dump of documents
The judge is a real weirdo. Remember the hearing where he called Flynn a traitor (I guess for working as a lobbyist for Turkey, how that is treasonous I never understood).. and then took a break, and came out and said "hey, sorry, about that treason thing I said - scratch that".
At times he's seemed very pro-Flynn, and at times very anti-Flynn. Regardless I don't think he has any choice.
It's like a cornerman throwing in the towel in boxing. The fight is over, but it's not officially over until the referee acknowledges that the towel has been thrown.
