The actions date to Hastert’s time as a Yorkville, Ill., high school wrestling coach and teacher, the official said.

“It goes back a long way, back to then,” the source said. “It has nothing to do with public corruption or a corruption scandal. Or to his time in office.”  Thursday’s indictment described the misconduct “against Individual A” as having “occurred years earlier.”

Asked why Hastert was making the payments, the official said it was to conceal Hastert’s past relationship with the male. “It was sex,’’ the source said. The other official confirmed that the misconduct involved sexual abuse.
