As negotiations on a same-sex marriage bill come down to the wire, New Yorkers United For Marriage announced today more business leaders are in favor of the measure.

Back in March, business leaders including Lloyd Blankfein of Goldman Sachs signaled their support for same-sex marriage in an open letter.

“As a company, Xerox values and benefits from creating a diverse, inclusive workplace that thrives on equal opportunity so our people and our business succeed,” said Dr. Sophie Vandebroek, Chief Technology Officer of Xerox. “We expect and believe our people deserve nothing less from the communities where they work and live. And, that’s why Xerox adds its full support for this bill so that our colleagues in New York State are afforded the equal rights they so rightly deserve.”
