Not taking issue with your post but one has to wonder whom they would have blown the whistle too? Their leadership, the press, the DOJ, congress, the president? I dont see any avenue for a whistle blower to address marxist sedition, subversion, and corruption in the FBI or any other government agency.
I would believe that would be in the realm of PDJT and his admin. The FBI works under the DOJ and the DOJ's final report is to the President of the United States. That is the way I see it.
