A group of Dallas-area families and faith leaders has filed a federal lawsuit seeking to block a new Texas law requiring the Ten Commandments in public school classrooms.

With the signing of Senate Bill 10, Texas becomes the second state to require the Ten Commandments in public school classrooms. Federal courts have already weighed in on a nearly identical Louisiana law.

Texas will soon require public school classrooms to prominently display the Ten Commandments under a newly signed law announced Saturday by Governor Greg Abbott. The measure makes Texas the largest state to implement such a mandate and is already drawing scrutiny from legal and civil liberties groups.
