I write separately to highlight another way in which this
prosecution may violate our constitutional structure. In
this case, the Attorney General purported to appoint a private citizen as Special Counsel to prosecute a former President on behalf of the United States. But, I am not sure that
any office for the Special Counsel has been “established by
Law,” as the Constitution requires.
Justice Thomas
