On Monday, one of the five people prosecutors say former Speaker of the House Dennis Hastert sexually abused filed a lawsuit claiming Hastert failed to pay off a secret $3.5 million dollar settlement, ABC News reports.

Disgraced former Speaker of the House Dennis Hastert quietly paid out millions of dollars in hush money because at least four minors lodged “credible accusations of sexual abuse” against him, a Chicago Tribune investigation finds.

Former Speaker of the House Dennis Hastert pleaded not guilty Tuesday to breaking federal banking laws by hiding as much as $3.5 million from federal authorities. Hastert, a former high school teacher, allegedly gave the “hush money” to a former student, who agreed not to reveal that Hastert had sexually abused him.
