Doesn’t matter once he offered to resign. Which Trump chose not to accept.
Ffs of course it mattered...who was going to take over as AG if Sessions resigned, some Obama holdover?
The GOP led Senate (most of whom were plotting against Trump) made it very clear they weren’t going to entertain another AG confirmation during that current term of Congress.
Jeff Sessions screwed Trump over royally...and it would not surprise me to find Sessions treachery against Trump extends all the way back to the campaign itself.
