Former House Speaker Dennis Hastert will have to report to prison on Wednesday for a 15 month sentence.
He'll be serving time at a federal medical prison in Rochester, Minnesota, about 350 miles from Chicago.
The Yorkville native is 74-years-old and in declining health.
At sentencing, a judge took into consideration a blood infection that nearly killed him late last year.
If he needs to, he'll be able to take advantage of the Mayo Clinic near the prison.
Hastert plead guilty last October to illegally funneling hush money in an attempt to cover up sex crimes he committed decades ago as a wrestling coach at Yorkville High School.
