Trump should just go truthfully answer all Mueller’s questions, and they can put this whole thing to rest.
Prosecutors don't ask questions they don't know the answers to, so why would he bother? Now Kanye on the other hand could meet with Mueller in his place and get put in witness-protection to save him from the Crips...a distraction horse-face Mueller would probably welcome since he's got bubkis on Trump.
If you had read the questions, then you would know that Mueller would not have the answers. They are questions such as what were you thinking, why did you say that, what was the reasoning behind your actions, etc. That’s why he needs to talk to trump.
