He has to go. He has failed the most basic duty of AG, which is to protect the president. Now he is failing the second duty, which is to go after the opposition party and its supporters. He should have gone after Lois Lerner and silicon valley monopolists already but nothing. He should have released all embarrassing Hillary/Comey/Lynch material but is actually fighting in court to keep it secret.
Bottom line, Sessions was a tough talker but he is a weak leader. Invisible leader actually. He was an early Trump supporter and Trump owes him, but there are limits. Put him somewhere where he won't do so much damage,.
