In an exchange in the state legislature, two representatives clashed over a plan to display posters of the commandments in classrooms.

Texas would require all public school classrooms to display the Ten Commandments under a Republican proposal that cleared a major vote Saturday and would make the state the nation’s largest to impose such a mandate.

A Republican-backed bill to require public schools to place the Ten Commandments in every classroom won preliminary approval Saturday. The vote was 88-49. The outcome sets the stage for the vote on final approval for Senate Bill 10 to happen Sunday.
