All of his decisions were calculated and he lied to Congress and usurped the chain of command. Session's was his bosses Boss and he acted as if he was in charge of Session's and the entire Justice Dept. He also has an ego where he thinks he is the smartest person in the room. He continues to be wrong, Major arrogance and delusions of grandeur. He though he was untouchable. His ego is evident in his good bye letter. He was such a political operative and tried to act as if he was neutral. He needs to just get a grip and let it go. Majority of people see him as a political hack.
It should be handled as a criminal matter.
