Why would we not put a Sunset provision into the Special Counsel law, such that once authorized , they have to be periodically REauthorized in order to keep working? We could make the authorizer Congress, or the Attorney General, or perhaps even some anonymous body of citizens convened as something like a jury. We could require whoever sets loose a Special Council that they provide the means for ending the investigation. Because what is happening now is ludicrous, by any standard.
Will Robert Mueller still be operating in 2020? Will he be investigating Trump’s reelection campaign while it happens? Will he be investigating the campaigns of all Republicans in 2018? How can we know? Where do his non-delineated powers end? When do they end? Maybe he could still be investigating 10 years from now, 15 years from now. Maybe he could appoint a replacement, and the research be continued until 2050, or the final death of our Constitutional Republic, which would certainly not last that long in such circumstances.
