We will know for sure if Barr is Sessions with a bagpipe or real when one of two tings happen. If he comes out with a blockbuster announcement OR Trump decides that will never happen and declassifies the mountain of stuff he is sitting on. When THAT happens we’ll know Trump has given up on Barr/Durham.
11am nothing so far
Barr does claim that before the election, the American people do deserve to know what happened.
I think Barr says this because, as you point out, Trump will declassify everything before the election. So Barr really has no choice.
