Yesterday, a high school principal in Georgia wrote to parents to say she was sorry for a bigoted freakout captured in a widely-shared viral video and also to let them know who the real racist is: Satan.

“The devil was in the house and came out from my mouth,” TNT Academy founder Nancy Gordeuk said via email on Saturday. “I deeply apologize for my racist comment and hope that forgiveness in in [sic] your hearts.”

According to one student, the trouble began when Gordeuk mistakenly dismissed the crowd early at a graduation ceremony on Friday. “She forgot the final speech,” graduate Donte Lambert told WXIA-TV. “Then she told everyone to come back.” From CNN:

The video shows Gordeuk standing at the podium in front of a live microphone as she says, “You people are being so rude, to not listen to this speech.”

As commotion grows in the audience, she blurts out, “Look who’s leaving, all the black people,” prompting cries from the audience and an even larger exodus.

The young woman who originally filmed the video, however, says Gordeuk’s behavior was bizarre throughout the evening, prompting her to take out her phone.

“She came up to the podium and was like, ‘If your baby’s crying, you need to do one of two things: you need to tape their mouth, or you need to get out because they shouldn’t be here anyway,’” Brooklyn Jacobs told WGCL-TV. “I was shocked. And for a second, I thought I was the only one. I’m looking around and everybody’s mouth is open. We’re all looking the same way.”
