The Logic of the Situation:
1. Nunes and the House GOP members negotiated in BAD FAITH when they demanded and received classified information from DOJ, then exposed that classified information to their members and then to the public.
2. Trumpy used that exposed classified information, through BAD FAITH negotiations, to smear the Department of Justice and the FBI.
3. Robert Mueller, now working for the FBI, knows that both the House GOP members AND Trumpy used classified information to sully and degrade the FBI and the entire system of justice. Mueller, based upon evidence, can now strike down any pretense of GOOD FAITH negotiations with Trumpy's legal team as they are negotiating with the Mueller's attorneys for a more "protective" deal for Trumpy.
4. Mueller can easily conclude that since Trumpy is in collusion with House members who negotiated in BAD FAITH, Trumpy, too, will risk BAD FAITH negotiations to further his agenda.
5. Mueller, then, is entirely justified in ending the negotiations with Trumpy's lawyers and issue a subpeona for Trumpy to appear, without his lawyers, before a Grand Jury to answer questions about Obstruction AND Conspiracy. Trumpy proved that he cannot be trusted in ANY negotiation setting.
