I agree firing him would be a BIG problem and he is doing a wonderful job destroying his own credibility.
None of the unlawfully discoursed GSA material can be used in court proceeding.
Even worse for Muller is that it will now be up to the special counsels office to prove that any investigative findings they develop were the not the result (in hole or in part) from leads originating from the unlawful disclosures.
That will be a impossible task.
This investigation just went POOF.
If I were Muller I would quietly wrap this up as fast as I can and salvage what is left of my reputation.
He's a political lawyer hack with a huge ego. He doesn't have the sense or the power to pull back from the cliff like us lil people!
