Donohue made an “OK” sign with his hand at the beginning of Tuesday's show, touching his forefinger to his thumb, and holding it to his chest. The gesture has been co-opted by white supremacist groups in recent years. “Regardless of his stated intent, the gesture is a racist dog whistle,” the letter states. “Some of the first people to notice this were not affiliated with Jeopardy! in any way — they were viewers who couldn’t believe what they’d seen, captured it on video, and shared it to Twitter. Among them were people of color who, needless to say, are attuned to racist messaging and not appreciative that the show allowed this symbol to be broadcast.” The letter also notes that in previous instances where contestants made a controversial gesture, they were asked to reshoot the introductions.
