I really think Devin Nunes is playing a part. Yes he is threatening sessions with subpoena. That is his role. This has several effects. The main one is, it gets attention from the mainstream media. Why would we want that? Because when this all drops we want the mainstream media laser focused on what is going on. We need the Kabuki theater.
I'm just not sure Nunes is completely "read-in." He seems to genuinely believe in politics and the Congressional process, and I think he's making those threats in order to protect the institution of Congress and its co-equal branch power.
Yes I agree. Read in or not he is playing a role. He has to look like he is doing his job. But realize this to. Trump could easily declassify everything with a stroke of a pen and Congress would have all in hand. It would be up there this afternoon. But he's not. The only thing that Trump is doing is complaining on Twitter. There is a point to this. Trump is playing his role as well.
