Believe the swamp has something on Sessions and that is why he is acting the way he is or he is just plain stupid and afraid.
It should be obvious by now that Sessions was a Trojan Horse in the Trump campaign. Even before being sworn in, Sessions set the whole chain of events in motion that led to Mueller's appointment. Rod Rosenstein was Sessions' pick for Deputy AG. Sessions and Rosenstein recommended Comey be fired. Rosenstein made the recommendation IN WRITING WITH DETAILED REASONS. When the President acted on that recommendation, Rosenstein promptly turned around and appointed Mueller who is investigating the firing as "obstruction of justice." That is ENTRAPMENT, which is illegal. None of that could have happened if Sessions was an honorable, ethical man.
