A vote in the U.S. Senate on legislation to codify same-sex marriage, following a surprise bipartisan approval in the U.S. House, now appears on track for consideration in September after lawmakers return from summer recess.

Questions emerged on when the Senate would take up the Respect for Marriage Act, which was advanced amid fears the U.S. Supreme Court would act to rescind same-sex marriage next after the decision overturning Roe v.

Wade, after the House voted 267-157 in favor of the bill. Among the “yes” votes were 47 Republicans, a full one-fourth of the caucus, which triggered momentum for a Senate vote on the legislation.
