An estimated 1,200 supporters of gay marriage rallied for its legalization in New York on Monday.

Governor Andrew Cuomo released the transcript of a robo-call he had recorded in support of making New York the sixth state to legalize the institution and sent Lieutenant Governor Bob Duffy to speak to the crowd attending gay rights group Empire State Pride Agenda's eleventh annual Equality and Justice Day in Albany.

“I want to make one thing perfectly clear, nobody in this state should ever question or underestimate Governor Cuomo's commitment to marriage equality,” Duffy told the crowd. “The governor has made marriage equality one of his top three legislative issues.”

Cuomo aides did not give a reason why he skipped the event, but insisted he's committed to passage of the legislation. The governor will make his pitch on the issue next week during the People First Tour.

“Marriage equality is an issue of civil rights. Of basic, basic, civil rights,” Duffy added.

Openly gay lawmakers Senator Thomas Duane and Assemblyman Daniel O'Donnell, who have carried gay marriage bills in the past, also spoke at the event.

Duane reminded the crowd that a gay marriage bill died in the Senate in 2009, when Democrats controlled the chamber.

“They would not vote in favor of our right to be married and they would not vote in favor of GENDA if the vote were held today,” Duane said, referring to a transgender protections bill, the Gender Expression Non-Discrimination Act. Last year, Duane called the Senate “a cesspool of homophobia and transphobia” after a key committee rejected GENDA.

Twenty-four-year-old Miss New York Claire Buffie said she was “a straight ally” who has a gay sister.

Gay marriage “is the civil rights issue of our generation,” she said.

State Senator Ruben Diaz Sr., the Senate's most vociferous opponent of marriage equality, and the National Organization for Marriage (NOM) will rally against the yet-to-be-introduced gay marriage bill at a Sunday rally in the Bronx.
