A local county is facing criticism for praying before public meetings.
A group based out of Wisconsin is warning Union County that it may sue.
The Freedom of Religion Foundation said it is unconstitutional and wants commissioners to stop praying.
The group said it violates separation of church and state.
Earlier this year the American Civil Liberties Union sued Rowan County commissioners for the same thing, but the commissioners agreed to continue opening their meetings with prayer regardless of the lawsuit.
