The Supreme Court on Wednesday is poised to consider the fate of death row inmate Richard Glossip, a rare death penalty case with even more unusual support from Oklahoma Republican Attorney General Gentner Drummond.

Drummond and defense attorneys for Glossip are set to appear at the Supreme Court on Wednesday seeking a new trial for Glossip, whose case has spanned nearly three decades. Glossip has long maintained his innocence in the 1997 murder of Barry Van Treese, a motel owner in Oklahoma City. The case will focus on whether Glossip received a fair trial.
