Maybe more specifically here in 28 U.S.C. §§ 526:

"The Attorney General may investigate the official acts, records, and accounts of...the United States attorneys, marshals, trustees..." (italics mine)

So Durham, with the Attorney General powers delegated to him by Barr, would prosecute the case against DoJ itself.

We joke about Durham but it's a big friggin deal that he is specifically working on human rights crimes and would act as AG in prosecuting them.

EDIT: I think the big open question, that would likely land in the Supreme Court, is what happens if Durham finds the current AG is potentially a criminal, or vice versa? Which would take precedence? Does a provision exist for this?
