I am not an attorney; the National Review’s Andrew C. McCarthy is both an attorney and a former Federal prosecutor. If you would understand the jesuitical reasoning upon which the law is based, his current column in NR will definitely help you do so.
McCarthy explains why, in his considered opinion, it is past time for Mueller to lay out (a) what, if anything, he has determined happened with Russian involvement in our elections and (b) who is under scrutiny as complicit therein. McCarthy makes a persuasive argument for an end to prosecutorial secrecy by the Mueller team.
