A one-time contributor to former Rep. Jesse Jackson Jr. who was also a figure in the scandal surrounding imprisoned former Gov. Rod Blagojevichpleaded guilty in a medical fraud case.
Raghuveer Nayak has struck a plea deal with federal prosecutors before a hearing Friday morning.
The agreement short circuits his trial, which was scheduled to start next month.
At Blagojevich's first corruption trial in 2010, prosecutors said a witness was prepared to testify that Jackson instructed Nayak to raise money for Blagojevich's campaign. In exchange, the Jackson supporters would allegedly ask Blagojevich for an appointment to President Barack Obama's former Senate seat.
Neither Nayak nor Jackson was charged in the Blagojevich case.
