(CHICAGO) Ahead of his sentencing hearing later this week, the person at the center of the criminal case against former House Speaker Dennis Hastert, has filed a lawsuit claiming breach of contract.

​Individual A, identified in the new lawsuit as “James Doe,” is seeking the remaining $1.8 million Hastert promised to pay him. The lawsuit was filed in Kendall County.

Hastert, who had claimed he was being extorted, promised to pay Individual A $3.5 million to cover up sexual misconduct from Hastert’s days as a teacher and wrestling coach at Yorkville High School. He pleaded guilty to violating banking laws after withdrawing large sums of money. He lied to the FBI about the cash, which was used to pay Individual A, who has collected $1.7 million so far.

Hastert will be sentenced Wednesday, where one victim and the sister of another victim are expected to testify. Attorneys have asked for probation for the 74-year-old. Prosecutors have asked for six months, but the judge could sentence Hastert to a maximum of five years in prison.
