At its spring meeting in Hollywood, California on Friday, the Republican National Committee (RNC) unanimously approved a resolution affirming the GOP's opposition to gay marriage.

“RNC members just unanimously approved 12 resolutions, including one that re-affirms party's opposition to same-sex marriage,” tweeted Chris Moody, political reporter for Yahoo! News.

National Committeewoman from Oklahoma Carolyn McLarty championed the measure, which is part of a package of resolutions that aim to “re-affirm conservative principles” in the Republican Party.

“[T]he Republican National Committee affirms its support for marriage as the union of one man and one woman, and as the optimum environment in which to raise healthy children for the future of America,” the “Resolution for Marriage and Children 2013” reads. “And be it further resolved, the Republican National Committee implores the U.S. Supreme Court to uphold the sanctity of marriage in its rulings on California's Proposition 8 and the Federal Defense of Marriage Act.”

Evan Wolfson, founder and president of Freedom to Marry, pointed to the recent endorsements of GOP Senators Rob Portman and Mark Kirk in criticizing the move.

"With Republican support for the freedom to marry increasing every day – aided by the journeys of leaders like Senators Mark Kirk and Rob Portman – the RNC is showing itself out of touch with this resolution,” Wolfson said in a statement. “A party that claims to value individual freedom, personal responsibility, family stability, and limited government should be embracing the freedom to marry, as have a growing majority of young Republicans. RNC leaders would do well to align themselves with these supporters, who represent the party’s future, instead of digging in against the right side of history.”
