Time will tell, but I’m not going all doom and gloom before the investigation even begins.
The DoJ has AFAIK not had even one cleansing purge, except for some self resignations.
Sessions appointed (and the Senate quickly approved) the Swamp Critter, RosenKrantz, as his assistant.
I’m sure the totally Left-Wing Civil Rights Division has not been touched.
Sessions will not be doing the investigating, the DoJ Swamp Creatures will be.
Be realistic; They won’t be doing squat to investigate any one to the left of Clarence Thomas.
