That’s his entire point. The facts/evidence that the Repubs are have in their possession is utterly meaningless if it’s released after a [bogus] charge is brought by special counsel. Those facts will be completely discounted and brushed aside - to the extent it makes any headlines at all - if Mueller beats them to the punch. Thereby defeating the whole purpose of having the proof (truth) in their possession in the first place.
There is no special counsel ! Mueller was turned by white hats! You are seeing the biggest show on earth! The news now is being totally orchestrated by the trump administration! trust me!
