 That might be a much better rule than what emerged in the lower courts here. We think it would be insufficient because, again, that long line of cases talking about using the president's motives and the intrusive sort of consideration of the president's motives as transforming acts to official and unofficial would come into play. And, of course, once you can make that allegation, all of a sudden you've opened the door. You no longer have a per se clear, bright-line rule. You have a determination in every single case.
