This fellow has blatantly violated the requirements of the law, often flying in the face of essentially a direct court order.

At what point does this sort of malfeasance become criminal activity?  At the very least, I would think that one of the federal judges who's orders he has ignored could hold him in contempt of court and throw him in jail.  I'm surprised no one has tried that yet.

To hell with trying to force him out of office through politics or public opinion. He's breaking the law.  Put him in prison.
