Anyone who has continued to grant security clearances to Hillary Clinton and Susan Rice ought to have been fired weeks ago. McMaster is either evil or stupid.
The Susan Rice thing is actually disinformation. She received access only to her work product, which she needs if she is being interrogated or brought before congress. She does not have access to all documents.
I think McMaster has problems in many areas, but there is a deliberate effort going on to demonize McMasters and remove him. The fact that lies are being used to accomplish this, rather than his actual problems, might inevitably lead to a backlash. Bannon could actually lose his job if he is in any way connected with this campaign.
