Cheryl Mills and Heather Samuelson "can't" be interviewed by DOJ's National Security Division, because they are NOW Hillary's attorneys, and any such interview would thus violate attorney-client privilege.
Very clever! It basically means that if you've been involved in deep-state filth, you can just get yourself hired as a lawyer for someone else involved in deep-state filth, and voila! You can santimoniously, self-righteously refuse to answer questions.
Any lawyerfags here who can comment on this? There has to be a workaround, surely…
