Trump gets in a room and pleads the 5th on every question, avoids a public spectacle.
Mueller gets nothing.
Or..... Dirt Bag Mueller submits his questions in writing and POTUS attorneys submit answers in writing—that is, the ones they decide to respond to.
No face to face conversations, Mueller will absolutely try to set a perjury trap.
This was talked about on Rush's show today. I believe Dershowitz or Napolitano said that Mueller could offer immunity on the topics, taking the 5th off the table, then trap him on something not covered in the immunity deal.
Interesting take...
