A new report reveals former US House speaker Dennis Hastert had sexually abused teenage boys at school in the 1970s.
The Chicago Tribune report says at least four people have made what law enforcement sources described as credible allegations of sexual abuse against Hastert.
The accusers are men and their allegations pertain to the period when they were teenagers and Hastert was their high school coach in Chicago.
The newspaper said it has identified three of the four men. One of them, who was a wrestling team equipment manager, died two decades ago. Two others were popular student-athletes.
The Illinois Republican has reportedly said in a court file that he "apologizes for his misconduct that occurred decades ago" and is "overwhelmed by the guilt."
The politician is accused of paying hush money to some victims to whitewash the scandal.
Hastert, who had already stood trial, is scheduled to be sentenced at the end of this month.
The 74-year-old became the longest-serving Republican speaker who retired from Congress in 2007 after running the chamber for eight years.
