One thing I remember. Gen. Flynn gave testimony or whatever the right word is on, IIRC, 19 different occasions, not for the Mueller stuff, for other (can’t remember exact word, please someone with a functioning memory help me).
In fact I think that is one of the most important things to happen because of the Mueller investigation. Gave Flynn a chance to testify - he knows where the bodies are buried.
Prob true, but has no bearing on the Mueller Report - that I know of.
