A woman says that her deceased brother is the Illinois man who was sexually abused by former House Speaker Dennis Hastert.

During an interview on ABC's "Good Morning America," Jolene Reinboldt Burdge accused Hastert of sexually abusing her brother, Stephen, while he was a student at an Illinois high school where Hastert worked as a wrestling coach in the 1970's.

The revelation comes a week after the former Republican House Speaker Dennis was indicted by federal prosecutors for allegedly concealing large cash withdrawals in order to keep "prior misconduct" secret and then lying about it to the FBI.

According to the indictment, the 73-year-old former congressman agreed to pay someone identified as "Individual A" a total of $3.5 million. Although the indictment does not explain the nature of the "past misconduct," it does detail the withdrawals and financial transactions that he made with the unnamed person. The indictment also states that he paid about $1.7 million from 2010 to 2014.

Federal law enforcement officials later revealed that Hastert used the payments as hush money to conceal allegations of sexual abuse from a former male student that he knew while he worked as a teacher, The Los Angeles Times reports.

"It goes back a long way, back to then," an official said. "It has nothing to do with public corruption or a corruption scandal. Or to his time in office." Instead, the official confirmed that the nature of the alleged misconduct "was sex."

The Illinois Republican has been accused of withdrawing $952,000 and paying the unidentified person to "compensate for and conceal his prior misconduct." Plus, he is accused of circumventing federal standards that requires banks to report withdrawals over $10,000.

When questioned by the FBI in December 2014, he allegedly lied and said he was keeping the cash because he did not trust the banking system, states the indictment.

As a result, Hastert was "charged with one count each of structuring currency transactions to evade currency transaction reports" in addition to giving the FBI a false statement, NBC News reports.

Mr. Hastert is scheduled to appear in court next week in Chicago.

Before being elected into office, Hastert worked as a high school teacher and coach in Yorkville, Illinois, from 1965 to 1981. It is during that time that Burdge says Hastert abused her brother.

She said she learned of the years of abuse once her brother left high school.

"I asked him, 'When was your first same-sex experience?' " she said. "He looked at me and said, 'It was with Dennis Hastert.' I was stunned."

"And he just turned around and kind of looked at me and said, 'Who is ever going to believe me?' "

Burdge said she believed the abuse ended after his high school graduation in 1971. He later died of AIDS in 1995.
