There’s only one known instance of a church losing its tax-exempt status because it violated the Johnson Amendment, but Republicans have tried to get rid of it before.

Ohio churches are having mixed reactions to news that the Internal Revenue Service will relax enforcement of the ban on churches as tax-exempt entities from endorsing political candidates.

The rule was introduced by former President Lyndon B. Johnson in 1954 when he was serving as the U.S. Senate majority leader. It banned all tax-exempt organizations like churches and charities from “directly or indirectly” participating in politics, specifically in endorsement or opposition of candidates.
