A group of 467 alleged former Jeopardy! participants issued an open letter on Medium Wednesday, demanding an apology from the show producers for not catching a “Jeopardy!” winner allegedly flashing a white power hand gesture. “A recent contestant has caused concern among ‘Jeopardy!’ viewers for two separate occurrences, and we, as former contestants, feel the need to speak out against the messaging that these choices communicated — either intentionally or unintentionally — by the contestant Kelly Donohue and, implicitly by association, the producers of ‘Jeopardy!’” the story said.
