 NPR's Claudio Grisales. Louisiana's new law requiring the Ten Commandments be displayed in public school classrooms is facing another legal challenge. Matt Bloom from member station WWNO reports opponents are asking a federal judge to block it. A group of nine Louisiana families along with the ACLU and Americans United for the Separation of Church and State filed the request for a preliminary injunction. Attorney Alex Luchinitzer says they hope to block the new law from taking effect before the new school year starts in the fall.
