New York Senator Ruben Diaz Sr. has said he will lead an effort to annul the marriages of gay couples marrying in New York City.

On Sunday, gay couples helped break a one-day marriage record in New York City as New York became the sixth – and most populous – state to allow gay and lesbian couples to marry. Judges who volunteered to officiate over the weddings waived the customary 24-hour waiting period.

The National Organization for Marriage's (NOM) “Let The People Vote” rally in Manhattan drew about 3,000 people who marched from Governor Andrew Cuomo's Manhattan office to the Dag Hammarskjold Plaza near the United Nations, where Diaz, also a Pentecostal minister, addressed the crowd.

Diaz said Mayor Michael Bloomberg was breaking the law by waiving the waiting period without a good reason.

“We're going to show them next week that everything they did today is criminal and it's wrong,” Diaz said in Spanish. “Today we start the battle! Today we start the war!”

NOM also held rallies in Albany, Rochester and Buffalo.

In Albany, NOM president Brian Brown told a crowd of roughly 400 that lawmakers had “put into statute a lie,” the Times-Union reported.
