Former Detroit Mayor Kwame Kilpatrick is asking the U.S. Supreme Court to overturn his corruption conviction and 28-year prison sentence.
The request was recently 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, but Kilpatrick wanted the full appeals court to hear the case.
Kilpatrick's attorney Harold Gurewitz had told The Detroit News afterward that the Supreme Court appeal was being planned.
Kilpatrick's appeal has centered on an alleged conflict among his trial attorneys, among other very technical reasons. He quit office in another scandal in 2008.
