The Denver Post said the hearing was to take place before 18th Judicial District Judge William Sylvester but it wasn't clear whether Holmes would be present.
The newspaper said if the media coalition's motion is granted the public would get a much better look at legal proceedings against Holmes.
Holmes is accused of killing 12 people and wounding 58 others July 20 at the Century Aurora16 theater during a showing of "The Dark Knight Rises."
