There will still be investigations, but they will not be public posturing.  You are going to wake up one day and all the news will be reporting how these persons were arrested by the FBI with warrants isssued by the DOJ for these crimes.  There will be a press confrence where Barr will detail out the arrests, and that will be the end of it other then minor new pieces throughout the various trials.  Unless if they go all the way to Obama, but even then it will not be the public spectacle the last two years has been.
