A group of business leaders and Hollywood celebrities are urging President Obama to support gay rights more strongly by backing same-sex marriage.

In a letter to the president released on Monday, actors, business leaders, athletes and media personalities asked Obama to “end discrimination in marriage.”

“We ask you now for your leadership on ending the exclusion of same-sex couples from marriage, an exclusion that harms millions of Americans each day. Whether to end discrimination in marriage is a question America has faced before, and faces again today,” the letter says. “With so many Americans talking it through in heartfelt conversations, it is a question that calls for clarity from the President.”

The letter, signed by media personality Ellen DeGeneres, musician Rufus Wainwright and businessman and philanthropist David Geffen, is part of the pro-gay-marriage organization Freedom to Marry’s “Say I Do” campaign.

Jane Lynch and Anne Hathaway are also listed as signatories. More on Freedom to Marry’s Say I Do campaign here.
