Special prosecutors are supposed to be appointed to investigate illegitimate or illegal activities of government servants.  Collusion may be unseemly, but it is not illegal.  What we have with Special Prosecutor Mueller is an investigation into ALLEGED unseemly conduct in search of a crime.   It has been more than a year since our intelligence agencies began their investigation into alleged Russian interference in the election and possible collusion between Russia and the Trump campaign.
