"IG email investigation (weakest of set)."

This is either one of the 4 versions RR picked out or is this IG report one of a set of IG reports?

I think I heard this was just one report out of 3 or 4 reports, this one was about Clinton emails and next will have a different topic, correct?

As I see it, a Grand jury decides if an indictment is good for trail or not and can be done without suspect even knowing about it? Correct?
