New York State Senator Ruben Diaz said Tuesday that he would co-sponsor a bill which would repeal the state's one-year-old gay marriage law.

The bill was introduced earlier this month by freshman Senator David Storobin.

In a memo attached to the bill, Storobin wrote: “The government has thrust upon the people of this state a definition of marriage that violates their religious and personal moral beliefs.”

In an e-mail to supporters, Diaz, the only Democrat to vote against the measure in the Senate, thanked Storobin for “giving me the opportunity to join him as a co-sponsor to this historic and pending piece of legislation.”

“You should also know that so far – as of today – it is only Senator Storobin and me who support this legislation. It will be a difficult and uphill battle. Nonetheless, our struggle will continue as we work to get 30 more senators to join us. We are not giving up.”

During a heated campaign to replace Carl Kruger, a closeted gay Democrat convicted on corruption charges, Storobin's opposition to marriage equality won him the endorsement of the National Organization for Marriage (NOM), the nation's most vociferous opponent of gay marriage.

Storobin attacked his rival, Democratic City Councilman Lew Fidler, for his support of gay marriage during the campaign. His position helped the Republican attorney turned politician win over a large Orthodox Jewish bloc in the district, The Wall Street Journal reported.

No companion bill has been filed in the Assembly, where marriage equality has more robust support.
