It means two things:
1. He is compromised.
2. He's not compromised and all this stuff is just for show.
Hard to see alternatives to those two.
Hard to believe Sessions is this incompetent, and was a long term Senator...
I’ll put my money on your second choice.
My opinion, I think Sessions is being blackmailed, I think someone has the goods on him and has kept him under a tight leash..NO WAY would Jeff Sessions, who I actually supported being Attorney General when his name was announced, would not have investigated the Clinton Crime Family, NO WAY something is up..the Clintons are very good at two things, offing you(And making it look like an accident), and getting the goods on you and owning you for life
another possibility
3. He’s submitted his resignation and Trump would not accept it.
I go for 2.
