It doesn't matter at all what all the people in this cabal did. It only matters whether or not anyone will file charges. And from what I have seen from Sessions so far, I'm not confident that anything substantive will happen.
The people involved may be fired, or censured, or reprimanded, or held in contempt, or whatever. But no criminal charges will be filed. That seems to be way it works these days.
Yes. They are guilty as hell. But we are not going to do anything about it.
