McCabe is gone. Several others involved have lost their positions of influence. Getting the facts out in the open may be all that is needed. No "firings" required. There is more than one way to bring pressure to bear. Ultimately, the FBI can be influenced by the need to repair its reputation by cleaning house. The memo seems like a good start. Get it all out in the sunshine.
No firings required?? Who is going to bring pressure to those who have been caught up in the corruption when the majority of those involved are corrupt? Rosenstein is the Deputy AG, the only person higher than him within the DOJ is Sessions. Sessions has been absolutely silent on this! Also, with the massive corruption, who is going to replace Rosenstein?
The corruption in the FBI runs deep as well, so who is going to clean house and who are you going to replace all these people with?
This is the problem that I see ... we have a multitude of people within the DOJ and the FBI that need to be removed, but they also need to be replaced. Who is going to replace them and with whom?
