So Mueller is fine with you telling congress about Trump crimes that you didn’t tell him?
I doubt he'll be spilling too many new beans:
February 7, 2019: "A federal judge in New York acknowledged in a court filing Thursday that "aspects" of a federal investigation into Michael Cohen "remain ongoing" nearly two months after the President's former fixer was sentenced to three years in prison.
The revelation came as part of a ruling issued by Judge William Pauley partially granting a request from various media organizations, including CNN, to unseal documents pertaining to the April 9, 2018, raid of Cohen's home, office and hotel room."
He told Mueller the same things. This hearing is just to give Mueller cover when he brings up the same allegations, but says the evidence for charges was sketchy and hard to find since it was likely destroyed.
