enough of the other creeps have sung to not require immunity for the main guilty party.
Remember when they gave a Hillary crony immunity to testify, and everyone thought the jig was up for Hillary.
The crony just came out and said that nothing illegal had happened, couldn’t recall, Hillary wasn’t there, Hillary did nothing wrong, etc.
That’s what I suspected this jerk would do if he got immunity.
The way to proceed with these traitorous criminals is to convict, sentence to prison, take into custody, lock in cell, AND only then approach with a deal offer.
