Sessions spent 12 years in DOJ as a prosecutor. From 1981 to 1993, he served as U.S. Attorney for the Southern District of Alabama. He was also the AG of Alabama. And he sat on the Senate Judiciary Committee for over a decade overseeing the operations of DOJ and the FBI. I would say he was well-qualified for the job.
Certainly makes sense but seems he is neglecting the big issues we have.
