Idaho’s Republican-dominated state House of Representatives voted 46-24 to pass a resolution to reject same-sex marriage, despite the U.S. Supreme Court's landmark ruling in Obergefell v Hodges.

In 2006, Idaho voters passed an amendment to the state Constitution to define marriage as a union between a man and a woman, though the Supreme Court’s ruling nearly a decade later found that such laws violate the 14th Amendment’s equal protection and due process guarantees.
