An anti-gay rights group is furious at New York Republican lawmakers for helping to legalize same sex marriage in the state.

A fundraising letter from the National Organization for Marriage (NOM) announced that the group plans multiple rallies in New York to begin a campaign to repeal marriage equality, which wassigned into law by Democratic New York Gov. Andrew Cuomo on June 24.

The group also launched an attack on Republicans who helped pass the law, saying that they "sold out the party's base, the party's principles, and the timeless institution of marriage."
