You remember last month when Comey had a ‘Senate Meeting’ and no one would talk about it? Did Comey talk to Jeff Sessions about this meeting BEFORE it happened? No he didn't, Sessions is his boss and then when Rosestein the Deputy A.G. was sworn in, he became Comey’s boss and never once in the Obama Administration did Comey go to them and tell them what he was doing...and neither did McCabe...
There are steps that you follow and one of the things that Comey was doing was building the FBI into a ‘closed’ department to take the Government down...
