DETROIT (AP) – The U.S. Supreme Court has declined a request by former Detroit Mayor Kwame Kilpatrick to overturn his corruption conviction and 28-year prison sentence.

The court announced its decision not to review the case Monday.

Kilpatrick’s request was made after a federal appeals court said in October it had no interest in taking a second look at the case.

His appeal centered on an alleged conflict among his trial attorneys, among other very technical reasons. He quit office in another scandal in 2008 and is federal prison.

Kilpatrick’s attorney, Harold Gurewitz, told the Detroit Free Press that he’s “disappointed that the court didn’t give” them “an opportunity to argue the issues of law” that were raised.
