WASHINGTON (AP) — The House is set to take a final vote on protections for same-sex marriages. The vote Thursday will send the legislation to President Joe Biden, a monumental step in a decadeslong battle for nationwide recognition of such unions that reflects a stunning turnaround in societal attitudes. A law requiring all states to recognize same-sex marriages would be a relief for hundreds of thousands of couples who have married since the Supreme Court’s 2015 decision legalizing the marriages. The bipartisan legislation would also protect interracial unions by requiring states to recognize legal marriages regardless of “sex, race, ethnicity, or national origin.”
