Following the Oklahoma Court of Criminal Appeals’ decision last year to uphold death row inmate Richard Glossip’s conviction, his case will be heard before the United States Supreme Court on Wednesday.

Twice in the past decade the Supreme Court has blocked Oklahoma from executing Richard Glossip. Now the state has joined Glossip to argue that newly uncovered evidence shows prosecutors violated his rights at trial.

When lawyers for Richard Glossip argue before the U.S. Supreme Court on Wednesday to vacate his conviction for a 1997 murder, the Oklahoma death row inmate will have an unlikely ally: Gentner Drummond,

The U.S. Supreme Court is set to hear the appeal of Oklahoma death row inmate Richard Glossip, spotlighting potential flaws in the state's criminal justice system.

The state’s Republican attorney general took the rare step of asking the Supreme Court to set aside Richard Glossip’s capital conviction.

After an appeals court overturned that conviction based on ineffective defense counsel, Glossip again was found guilty of first-degree murder in a 2004 retrial. Glossip is asking the Supreme Court to grant him a new trial after an Oklahoma court refused to overturn his conviction despite potentially exculpatory evidence being recently uncovered.
