A Texas man named Duane Buck, convicted of murdering two people, has been sentenced to die. He's asked an appeals court to grant him a new sentencing hearing.
Buck's appeal is supported by a broad coalition of individuals and organizations, including a former Texas governor and one of the prosecutors who convicted him. They're not arguing for a new hearing because he's innocent – there are no doubts that he committed murder.
Instead, supporters argue that Buck is on death row because he's African American, and they point to testimony that jurors heard from an expert witness. CNN's Ed Lavandera reports.
