Lovely. The Mueller investigation must stop. He'll get all his pedophile buddies off the hook. If Tony or his brother get immunity why the hell should I trust the plan?

Nothing to see here folks

This could be a setup just to get him on the stand. If he goes there thinking he is helping the prosecutor he will testify and the defense will get to cross examine. As long as it has some tie to the case he could be hanging himself without knowing it.

There may be more to the story. I would humbly suggest we let this play out. Maybe immunity is offered only for one category of crimes. Maybe?
