A total of 14 cadets have been dismissed, suspended or are receiving on-campus punishment at The Citadel military college in South Carolina after a group appeared in photos with pillowcases on their heads similar to Ku Klux Klan garb.

College President retired Air Force Lt. Gen. John Rosa announced the decision Monday.

Photos of seven freshmen cadets dressed in white pants and shirts while wearing pillowcases on their heads surfaced on social media last month.

The investigation determined that the freshmen were ordered by upperclassmen to sing Christmas carols dressed in costumes. The photos in question involved a "Ghosts of Christmas Past" skit.

Rosa says that the incident showed poor judgment and that the college will increase diversity training for cadets.
