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. The Associated Press left a message seeking comment from a lawyer for Kilpatrick.

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.

In 2013, Kilpatrick was found guilty of two dozen crimes, including tax evasion and bribery. A three-judge panel of the 6th U.S. Circuit Court of Appeals in August affirmed the conviction.
