 Well, I don't think Richard is really far off the mark here. The Chief Justice gave a high-level description of the three categories in which the president's immunity comes into play. So the first category are those conclusive and preclusive areas of constitutional authority. So those are identified in Article II. And in those situations, the president is entitled, the court says, to absolute immunity from criminal prosecution. And then there are these categories that involve purely private activity. In those circumstances, the president is not entitled to immunity.
