A photo from the event appears to show Landrieu—one of the most vulnerable Democratic incumbents this year— holding the keg’s spigot while a young man dressed in the Tigers’ purple and gold does a handstand on the keg and other participants hold his legs. A crowd of onlookers cheers him on.

A source close to the campaign said the man was in his late 20s and was enjoying a tailgate with his friends and family. The source also said his father was at the tailgating party with him.
