Dennis Hastert agreed to pay $3.5 million to a person the former House speaker sexually abused when the victim was a 14-year-old wrestler on a team coached by Hastert, prosecutors said in a court filing Friday that details allegations by five former students.

The filing is the first time prosecutors have confirmed Hastert paid hush-money to conceal sex abuse. It chronicles a chain of deception that began with Hastert exploiting his position of trust as a teacher and coach and carried on years later to include lying to bank officials and making false claims of extortion to the FBI to conceal his wrongdoing.

The filing recommends that a federal judge sentence Hastert to up to six months in prison for violating banking laws as he sought to pay one of his victims, identified in court documents as "Individual A," to ensure the person kept quiet. The sex-abuse allegations date to Hastert's time at Yorkville High School in the Chicago suburb of Yorkville from 1965 to 1981.

"While defendant achieved great success, reaping all the benefits that went with it, these boys struggled, and all are still struggling now with what defendant did to them. Some have managed better than others, but all of them carry the scars defendant inflicted upon them," the filing says.

Prosecutors say Hastert still was abusing boys when he first decided to run for office, but the now-74-year-old Republican managed to keep any hint of sexual misconduct quiet throughout a political career that carried him from the Illinois Legislature to the halls of Congress and eventually to the speaker's office, where he was second in the line of succession to the presidency.

Hastert, who pleaded guilty in October to breaking banking laws, is scheduled to be sentenced April 27. The defense has asked the judge to give Hastert probation and spare him prison time, citing Hastert's deteriorating health and the public shame he's already suffered.

Defense attorney Thomas Green said Saturday: "Mr. Hastert acknowledges that as a young man he committed transgressions for which he is profoundly sorry. He earnestly apologizes to his former students, family, friends, previous constituents and all others affected by the harm his actions have caused."

Green also argued again that Hastert has over the past four decades "made every effort to be a positive force in the lives of others and said that the situation has led to his "frail medical condition."

Individual A is one of at least four people cited in the filing as saying that Hastert sexually abused them as children. Three were wrestlers and the fourth was a student-manager on the team Hastert coached. 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.

Prosecutors say in the filing that Hastert's known sexual acts against Individual A and other accusers consist of "intentional touching of minors' groin area and genitals or oral sex with a minor."

According to the document, Individual A told prosecutors the abuse occurred in a motel room on the way home from wrestling camp. Hastert, the only adult on the trip, told the 14-year-old that he would stay in his room while about a dozen 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.

The other former wrestlers told prosecutors Hastert touched them in the locker room at Yorkville High, after saying he would give them massages. Two of those wrestlers, who were ages 14 and 17, say Hastert performed sex acts on them.

The student-manager was Stephen Reinboldt, who died in 1995, and whose sister, Jolene Burdge, has spoken to The Associated Press. Burdge said her brother told her that the sexual abuse lasted throughout his time at Yorkville.

In their filing, prosecutors wrote that Hastert's "history and characteristics are marred by stunning hypocrisy." He made his victims "feel alone, ashamed, guilty and devoid of dignity," they said.

Prosecutors noted the statute of limitation on any sex-abuse charges have long since run out, making the banking charges the only ones they could pursue.

"The government seeks to hold defendant accountable for the crimes he committed that can still be prosecuted," the filing says.

Hastert made 15 withdrawals of $50,000 — for a total of $750,000 — from 2010 to 2012. It's what he did next that made his actions a crime. After learning withdrawals over $10,000 are flagged, he withdrew cash in smaller increments, taking out $952,000 from 2012 to 2014.

The case has been shrouded in secrecy since Hastert was indicted in May 2015. Prosecutors only confirmed at a March hearing that sex-abuse claims were at its core.

Hastert's fear, prosecutors said Friday, was that if he didn't pay Individual A "it would increase the chance that other former students he molested would tell their stories." Burdge had already confronted Hastert at her brother's funeral and he could see "she had been deeply affected by what defendant did to her brother, and she was likely to tell her story publicly if anyone would listen."

Court records say Hastert managed to pay $1.7 million to Individual A — handing it over in lump sums of $100,000 cash — starting in 2010. The payments stopped late in 2014 after FBI agents questioned Hastert about his cash withdrawals. Prosecutors said Friday that it was a bank compliance officer who spotted the huge withdrawals.

Pressed about the withdrawals, Hastert gave various explanations for what he was doing with the cash — that it was for vintage cars and for stocks, that he didn't trust the banks — before he claimed he was be being extorted by someone he said was making a false sex-abuse claim. Hastert agreed to let investigators record phone conversations he had with the man, and prosecutors concluded the man's tone and comments "were inconsistent with someone committing extortion."

Days after pleading guilty, Hastert entered the hospital and nearly died from a blood infection, according to his lawyers. They also say he had a stroke and required in-home care.
