It would be unwise to fire Session since it would further the Democrat’s false narrative of Trump interfering in an investigation (an investigation which itself is a false narrative) and would give them their lusted after “Saturday night massacre”. Firing Sessions would be a dream come true for Democrats.
So you think Trump shouldn't have fired Comey?
If Sessions is not willing to take on the Deep State corruption, then Trump should fire him. It would "further" the goals of the Deep State if he didn't.
