Everything to know about the Respect for Marriage Act and the new battle for same-sex marriage

• The House this week codified same-sex marriage amid growing concerns that the U.S. Supreme Court might revisit its landmark 2015 decision protecting gay marriage rights.
• By overturning national abortion rights, one advocate said the court showed “a willingness to overturn precedent that forms a critical part of how the majority of Americans understand our freedom and society today.”
• There are approximately 513,000 married same-sex couples in the United States.

The House passed the Respect for Marriage Act this week, codifying federal protections for same-sex marriage in the wake of concerns among lawmakers and LGBTQ advocates that the U.S. Supreme Court might reassess its landmark 2015 decision making gay marriage the law of the land.

All 220 House Democrats voted in favor, with 47 Republicans also in support. Now, the measure heads to the Senate, where it is unclear whether it can win over enough Republicans and advance to the White House.
