The husband of an Oklahoma mayor thought it would just be a hilarious laugh with friends when they donned white sheets to dress up as the Ku Klux Klan, complete with burning torches.

Lahoma, Okla., Mayor Theresa Sharp is now apologizing for her husband, Cary Sharp’s, actions, which prompted alarm in their neighborhood. “A cousin of mine came up with the idea of dressing up like KKK members and so we took a couple of sheets and cut holes in them and wore the sheets, and it was a very, very poor decision,” he said.

“I never realized it would have been so harmful,” he added. “I truly apologize to everybody for this.”

Outraged residents are calling for some action to be taken.

“It’s not OK for anybody,” one resident, who did not want to be seen on camera, told KOCO. “The mayor needs to take responsibility for what her husband did.”

The Garfield County Sheriff’s Office said no crime was committed, while acknowledging the costumes were in poor taste. However, the sheriff told the station that the case may be turned over to the district attorney’s office for review.
