In July 2013, Blagojevich filed an appeal with the United States Court of Appeals for the Seventh Circuit in Chicago challenging the corruption conviction and the length of his prison term. A three-judge panel of the Seventh Circuit heard arguments in the case in December 2013. In July 2015, the court unanimously vacated five of the corruption convictions, including his convictions for attempting to sell Barack Obama's vacant U.S. Senate seat after he was elected president, but affirmed the rest. The court's decision remanded to the district court. The Seventh Circuit denied Blagojevich's request for rehearing "en banc", and in March 2016, the Supreme Court of the United States denied Blagojevich's petition for a writ of certiorari.
