The husband of the GOP candidate running for Congress in Georgia’s 6th Congressional District tweeted a meme urging voters to “Free The Black Slaves From The Democratic Plantation.”

A spokesperson for Karen Handel’s campaign told CNN that Steve Handel’s reposting of the message with his own commentary was a “mistake,” and that Steve Handel had “retweeted something he didn’t pay a lot of attention to, thinking it was just an absentee vote message. It clearly was not appropriate and has been deleted.”

CNN posted screen captures of both Steve Handel’s retweet, and the original post:

Handel is currently in a run-off election with Democrat Jon Ossoff to determine who will fill Secretary Health and Human Services Tom Price’s vacant seat in Congress.
