Lawyers for the man charged with killing 12 people in a Colorado movie theater have asked the U.S. Supreme Court to compel a Fox News reporter to identify her sources for a story about the defendant.

The attorneys said Monday they asked the justices to review a New York state court ruling that Colorado cannot force New York-based reporter Jana Winter to reveal who told her that Holmes sent his psychiatrist a notebook containing violent images before the July 2012 attack (See Petition).
