I don't recall who has passed that cause the governor to order flags to be flown at half-staff. Now, I'm no expert on the US flag code, but I don't think it requires that ALL flags are flown at half staff when ordered. Or perhaps an elf or reindeer had a tragic accident and St. Nick requested this. Who knows?
