Huber is not testifying tomorrow because he doesn't need to yet. The whistleblowers deserve the focus and news coverage.
Huber is the counter-punch when the DS thinks they can spin the whistleblower testimony.
Always leave one in the chamber.
Moves and countermoves.
Huber has already completed his investigation, otherwise the whistleblowers wouldn't be allowed to comment upon an ongoing investigation.
Grand Jury has likely already been impaneled.
I understand your point, but to me that just says that's how much of a closed case it is. There is no way the Clinton's can wiggle out of this one, so there's not need to hold back the hand at play.
They are toast.
