In the United States, a special counsel is a lawyer appointed to investigate, and potentially prosecute, a particular case of suspected wrongdoing for which a conflict of interest exists for the usual prosecuting authority. Other jurisdictions have similar systems. For example, the investigation of an allegation against a sitting president or attorney general might be handled by a special prosecutor rather than by an ordinary prosecutor who would otherwise be in the position of investigating his or her own superior. Special prosecutors also have handled investigations into those connected to the government but not in a position of direct authority over the Justice Department's prosecutors, such as cabinet secretaries or election campaigns.
