When Trump decided to run again his status changed from a septuagenarian private citizen in Florida to a presidential candidate. The current president has stated that he wants to run again so they are adversaries. The DOJ and FBI who are under the control of the current president can’t investigate because of conflict of interest. Can the Congress investigate him? Not sure they can. Certainly Congress and their Jan 6 committee could be seen as interfering with the investigation of the Special Council.
Tough luck. Appointment of a Special Counsel was strictly for POLITICAL reasons. With a new Jan 6 Committee investigating the FACTS of what REALLY happened that day, it is going to make the Special Counsel "investigation" look ridiculous when the REAL FACTS are revealed.
