The late Steve Reinboldt was the student equipment manager on the high school wrestling team coached by Dennis Hastert in the late 1960s and early 1970s. In an exclusive interview with ABC News, Reinboldt's sister, Jolene, said that years later, her brother told her Hastert had sexually abused him throughout his high school years. Hastert, already indicted for alleged paying off another purported victim of his "misconduct," has not responded to the allegations against him.
