Dennis Hastert paid hush-money in effort to hide sex abuse of 14-year-old, prosecutors say

Individual A is one of at least four people cited in Friday's filing as saying that Hastert sexually abused them as children. Three were wrestlers on a team Hastert coached and the fourth was a student-manager. Another wrestler said Hastert touched his genitals while he was on a locker room massage table, but he wasn't sure if it was intentional.

According to the document, Individual A told prosecutors the abuse occurred in a motel room on the way home from a trip to wrestling camp. Between 10 and 14 boys were on the trip. Hastert, the only adult on the trip, told the 14-year-old that he would stay in his room while the other boys stayed in a different room. Individual A said Hastert touched him inappropriately after suggesting he would massage a groin injury the boy had complained about earlier.
