KEY POINTS:
A judge has sentenced Kwame Kilpatrick to 120 days in jail over charges the former Detroit mayor lied in a civil lawsuit about an affair.
The Democratic ex-mayor pleaded guilty last month to obstruction of justice, admitting he lied about an affair with his chief of staff while testifying in a civil lawsuit in 2007.
He also pleaded no contest to assaulting a sheriff's detective.
The 38-year-old Kilpatrick left office on September 18 after nearly seven years as mayor.
