Very possible at this point. I doubt Sessions has done anything of major importance. Now Trump is taking the fight to the Swamp. It seems like Sessions is slowly playing along. By no means is he in charge. He is causing more hinderence than help.
I believe the case is probably air tight already. It doesn’t hurt to be more careful but at this point who cares. A year has been wasted and finally Trump has them ready to “fall apart”. Sessions is along for the ride. Pretty sure he is being blackmailed.
Problem that has come up in all administrations is for Democrats, they weaponize the DOJ and for the Republicans, the Democrats paralyze the DOJ so the Republicans cannot prosecute the Democrats. I don’t think the Republicans figured this out yet.
Sessions has been hampered due to being overwhelmed with investigations and not enough IG’s to handle the workload. This means he has to prioritize and while most of us want to see Hillary locked up, that probably isn’t his number one priority.
