It's not about removing him. It's about gaining access to Mueller's stock of intel. They want it all--search warrant findings, subpoena findings, FISA findings, grand jury materials, raw interview notes, intel database queries/responses. You are talking about literally millions of documents for them to comb through and give to the media for a one year smear. It is opposition research funded by the taxpayers under the guise of a special counsel investigation. Imagine the Steele crap on steroids. That's Mueller's trove. That's what they are fighting for. Just my opinion, of course.
