Democratic Colorado Gov. Jared Polis is defending the “Don’t Tread On Me” flag in response to a now-viral video showing a 12-year-old student being told by school officials to remove a patch depicting it from his backpack.

Video of the incident sparked a social media uproar on Tuesday after it conservator author Connor Boyack posted it on X, formerly Twitter. The video, which appears to be filmed covertly by the boy’s mother, shows a school official explaining that the student was barred from displaying the flag, also known as the Gadsden flag, because school staff believed it to be associated with slavery and racism.
