How is your insistence that “something even worse will be revealed” not a conspiracy theory? It’s almost literally the definition!
DOJ's internal investigation already showed lots of violation of its protocol. Durham made clear his investigation is not limited to within the DOJ/FBI, of course he found more damning evidence that's why he made this statement. Otherwise how would you logically interpret? Investigation outside of DOJ/FBI makes DOJ/FBI look better?
"literally the definition"? You have a weird definition of "conspiracy theory". Every interpretation does not fit with your narrative is a conspiracy theory?
