This is a question of fact. The fact lies in whether or not the President had intestinal distress or if he or she had something else. This is a question that can be answered with a specific result, instead of a value judgment that could lead to shades of grey: "Yes, the President had stomach flu," or "No, it was actually pneumonia that led to the cancellation of the rally." These are measurable responses based in fact, without supposition.
