My fear is that Mueller will have his all Democrat grand jury indict Trump on some unrelated financial crime, and that he will be forced to stand trial before a Democrat judge and an all Democrat jury. There is no way he would escape conviction under these circumstances.
Facing this, he may be forced to resign in exchange for dropping the charges, regardless of how bogus the charges may be.
There is a reason Mueller moved the proceedings from the grand jury in northern VA to DC. The jury went from being racially and politically diverse to being all Black and All Democrat.
Just in case you’re point is accurate, there is the ability to request a change of venue.
Maybe Mueller plans to do that to Trump. No matter how ridiculous the charge, it would give Paul Ryan a green light to start impeachment proceedings.
