Hillary will probably have David Kendall or someone to that effect and they will limit anything and everything they possibly can from the FBI questioning. They will try and take as much of the table as I can that’s usually the game they play. NFL doesn’t work then I’ll claim top secret or national security or some such BS and usually they get away with it. difficult for anyone with her much money power and influence to ever get any jeopardy at all it just doesn’t happen.
In real life, the FBI would be investigating Kendall. So that would be ineffectual.
But alas, Kendall is connected so your scenario is the more likely.
