Wayne County Circuit Judge David Groner said Kilpatrick "challenged this court's authority" with his behavior, The Detroit News reported. The judge said Kilpatrick must spend at least 14 months behind bars.
"Probation is no longer an option. The terms of your earlier probation no longer apply. That ship has sailed," Groner said. "This is all because of the actions of you, Mr. Kilpatrick. You were convicted ... all because you lied under oath. That lie ... was part of a broader attempt to cover up your misdeeds while serving as mayor."
Kilpatrick admitted lying on a deposition about his part in firing police officers and his sexual relationship with his former chief of staff. His plea agreement included a short jail term and restitution to the city of Detroit.
He was taken out of the courtroom in handcuffs.
Kilpatrick, who said he is a "human being, a real-life flesh-and-blood person," apologized for his actions. He talked of the difficulty of knowing his children were subjected to ridicule.
