In a letter to U.S. District Judge James Zagel contained in court documents filed Monday, Patti Blagojevich wrote she is "pleading, indeed begging" that her husband be freed.
Blagojevich also recounted the milestones her husband has missed with their two daughters since being incarcerated in 2012.
A resentencing hearing is scheduled Tuesday in Chicago federal court after an appeals court struck down five of his 18 convictions. The 59-year-old Democrat will appear at the hearing via a video link.
Zagel also received a letter from Blagojevich's father-in-law, former Chicago Alderman Richard Mell.
Prosecutors want Zagel to impose the same term, saying Blagojevich doesn't deserve leniency.
