The former student, referred to in the lawsuit only as "James Doe," filed suit in county court in Yorkville, Illinois – the same town where Hastert was a teacher and wrestling coach at Yorkville High School from 1965 to 1981 – demanding the ex-Speaker pay the remaining $1.8 million to settle the sexual abuse allegation.
According to Politico, James Doe is the "Individual A" listed in a federal indictment of Hastert last year for illegally structuring cash withdrawals to evade bank currency-reporting requirements. Hastert pleaded guilty to that charge and is set to be sentenced for the illegal transactions on Wednesday.

In the new lawsuit filed Monday, the former student accuses the politician, described as a "trusted friend of Doe's family," of sexually abusing him at a motel while on a wrestling trip for high school students organized by Hastert.
The lawsuit says the abuse had long-term ramifications for the man, alleging: "For many years to follow, Plaintiff suffered severe panic attacks which lead [sic] to periods of unemployment, career changes, bouts of depression, hospitalization, and long-term psychiatric treatment."
The suit alleges: "In December, 2014, after Hastert's numerous cash withdrawals became the subject of Federal criminal charges against Hastert, Hastert breached the Settlement Agreement by failing to pay the remaining amount owed."
Federal officials say Hastert paid the alleged victim $1.7 million in cash before the FBI began investigating his unusual bank withdrawals.
Hastert's lawyers declined comment to PEOPLE.
