A mother says her son got in trouble for wearing his Duck Dynasty T-shirt to school, according to video from WWBT.

The popular show featuring a group of bearded millionaires is a hit on the A&E network, but the mother says her teenager was told the shirt was threatening to other kids at Dinwiddie High School.

“For this to be considered as a threat to the school … I couldn’t understand it,” Edna-Jo Spain tells WWBT.

Spain was outraged when teachers at Dinwiddie High School forced her son to remove the shirt, which shows a character from the reality television show Duck Dynasty clinching his fist.
