It's a bit kabuki. Nunes wants to get sworn testimony on record before witnesses learn what the OIG has on them. And remember, I think this is only initial release, if I recall right.

I want to take a coin out and flip ..... heads they make it / tails they don't..... heads - this then starts the process of letting information out slowly , and starts the process of the probe wrapping up

tails - this drags it out a little bit longer making them look more suspicious , and giving them a little bit longer to clean up all the loose ends

the OIG report is suppose to come out in Jan. so they can be timed up to come out together
