How many others will we see in those emails from the Obama Administration?

Whats behind curtain number three? Who else involved when we get those emails he used fake names for? Obama and Joe have to give permission under presidential records act for archives to release them to congress to see who else was on as addees. Wow, so now they care about presidential records act when its not against Trump and it's their advantage? Is this why republicans being so slow and cautious (interpret as fear). They might have two presidential investigations instead of just one!
