Does he get out of jail if hung jury...
I would think not, because it's the other judge who put him in jail for conduct she decided was relevant and against her orders in HER case. He wouldn't be in jail before trial if the only judge was Ellis.
So, a hung jury does not get him out of jail. In fact, it doesn't even mean that this set of charges goes away, because the government (i.e., Mueller) can decide to retry the case.
We want not guilty on all charges based on reasonable doubt because EACH AND EVERY witness was tainted.
It would be up to the judge's discretion, but I'm not sure which judge sent him there. Was it this judge or the DC judge?
