His "Honorable collage and dear friend" Mr Al "Diaper" Franklin said that he should and so Sessions did what he years of training in the senate told him to do. He barked and rolled over.
This is why senators are worthless after a couple of terms.
That seems to be the case. Now what I still don't understand is why Republicans do this to themselves. Sessions recuses himself after meeting the Russian ambassador at a cocktail party. Holder and Lynch on the other hand hold meetings with the Clintons while supposedly investigating them, hold meetings with #BLM while they are rioting in the streets, coordinate with DNC on public management of Clinton's email scandal, etc...
