Here's the *latest* list of what the DOJ Inspector General's office is investigating:
So this entry has appeared every month since April, 2018.
McCabe was fired for criminal leaks. So was Strzok.
Lisa Page & Baker were allowed to resign.
There were several cases where the OIG investigated, found FBI personnel engaged in gross violation of FBI/DOJ rules & procedures, presented it's case...and then nothing happened to the person. Usually just a quiet resignation.
