Because they are whitehats.
You really think POTUS would make him AG if he was evil, and going to help take him down, ( i don't fucking think so)
Mueller is putting on a show. Msm and the dems have been defending Mueller, sayting we must accept his findings.
What would be more glorious than Mueller finishing his investigation and unloading a shit ton of indictments on the Clintons, DNC, leakers, DS assholes, etc
ENJOYING THE SHOW
