At a recent rally where Barack Obama endorsed Sherrod Brown and Amy Acton, attendees chanted "Free Luigi" in apparent support of Luigi Mangione, accused of fatally shooting UnitedHealthcare CEO Brian Thompson in Manhattan. Conservative commentator Laura Loomer claims Brown stood on stage grinning during the chants rather than condemning the killing. The incident highlights escalating partisan tensions over public reactions to Mangione, who has become a polarizing figure online since his December arrest. Brown's campaign has not yet commented on the rally incident.
