If passed, the bill would require the U.S. Congress to formally declare war to deploy South Dakota National Guard members.

A bill that would make it mandatory for the Ten Commandments to be displayed in publicly funded elementary, middle and high schools passed out of the state Senate in a razor-thin vote on Tuesday. South Dakota Senators advanced SB 51 on an 18-17 vote.

First-term Republican Sen. John Carley of Piedmont brought Senate Bill 51, which is similar to legislation that’s popped up in North Dakota, Oklahoma, Texas and Louisiana. Louisiana in particular has a new law requiring schools to post the Ten Commandments, but that’s been stopped by a lower court.
