CHICAGO — Former House Speaker Dennis Hastert has officially completed his 15-month prison sentence and the 75-year-old is no longer being monitored by law enforcement.

Bureau of Prisons records indicate that Wednesday was the end of Hastert’s period in federal custody. Illinois’ Lake County Sheriff’s Office says it stopped electronically monitoring him Wednesday morning. He now begins two years of probation.

Hastert pleaded guilty to banking violations in a hush-money case that revealed he sexually abused several high school students.

He left a Minnesota federal prison on July 17, when he was fitted with an electronic device typically used when someone is under home confinement. It isn’t clear whether Hastert was, in fact, at his home in suburban Chicago.
