attorney general. if he fires rosenstein, his responsibilities for the mueller investigation would go from deputy attorney general, which is what he is, to the associate attorney general, which is what rachel brand is. so she s the next person in line to assusupervise the mueller investigation. if she s gone and mueller is fired, then it gets confusing about who is the supervisor of the mueller office. there would have to be new people nominated. i would have to check the statute about how far down in the justice department hierarchy it would go to who controls rod rosenstein. everyone had assumed that she would stay in the administration for longer than barely a year. she s only been on the job nine months. quite curious.
