re: So is Mueller going to testify or not? He's been a ghost as far as public appearances go.

Mueller has to avoid all of these topics under oath if he can...

Mueller would have to explain why they wanted to interview Trump well after they accepted no collusion occurred.

Why they avoided discussion in the collusion parts that painted the FBI (and Fusion gps) in a bad light.

Why they neglected to discuss the intelligence ties of many of those that were involved and how all of this swirls around the FISA court

Why they knew there was no collusion early on and yet continued the investigation for as long as they did

Why did he staff his special council with so many people that were directly tied to the Clinton and Trump investigations

Why did he selectively investigate and prosecute parts of the collusion narrative and not others (Podesta etc)

What was the official mandate and when was it determined


There are so many land mines in this that it would be a blood bath if he does appear
