A case involving a Ten Commandments monument at an Oklahoma courthouse may be headed to the U.S. Supreme Court.
    
Attorneys with the religious rights group the Alliance Defense Fund are asking for the review of a ruling last June.
    
An appeals court decided that the eight-foot granite monument on the Haskell County courthouse lawn violates the Constitution.

Judges were split 6-6 on their vote, missing the needed seven votes to overturn the ruling.
    
The American Civil Liberties Union and a local resident had argued the monument was endorsing religion.
