Bannon had McMaster's number from the get-go.  When he was still involved w/Breitbart, he would always refer to him as McMaster of Disguise.  With Bannon out of the picture, McMaster had more power w/POTUS. Comey has deep roots with Coats too.  Coats was a lobbyist for Lockheed Martin when Comey was the General Counsel.  You can just imagine the government contracts that were green lit with these two.
