Mueller stonewalled the Congressional committee regarding the biased FBI agent so he could get the plea agreement in otherwise it would have been premised on a flake. Now Muellhead has to stay the course as a fait accomplis. Justice must not only be done it must be seen to be done. And here the latter needs to be remedied with a pardon.
Funny how all of this info has come out only after Flynn's announced guilty plea on Friday. Had this all come out on Thursday, the charges against Flynn would have to be dropped and the Mueller investigation totally discredited.
