An Iowa Civil Rights Commission brochure that some churches interpreted to mean they must abide by transgender bathroom rules has been changed.

The commission said Friday that the brochure, which was last updated in 2008, has been reworded to make it clear places of worship are generally exempt from Iowa's antidiscrimination law except when they're open for voting, providing a day care facility or other non-religious activities.

The brochure led the Fort Des Moines Church of Christ in Des Moines to file a lawsuit Monday and Cornerstone World Outreach Church in Sioux City to threaten to sue.

The commission said Friday it's done nothing to suggest it would push churches on the issue.

A group representing the Sioux City church says it takes the state at its word but will pursue legal action if necessary.
