Hollywood moguls David Geffen and Steve Bing are being credited with launching the lawsuit challenging the constitutionality of Proposition 8, California's gay marriage ban.

In an interview with Variety, Chad Griffin, the former president of the American Foundation for Equal Rights (AFER), the group formed specifically to support the case, credited the business leaders with bankrolling the case.

“The leaders of the entertainment industry have been at the forefront of the civil rights movement,” Griffin said. “They were there through the '50s and '60s, and they have been there throughout the LGBT struggle for rights.”

“Folks in the entertainment industry are really stepping up from a philanthropic perspective [as well].”

“Were it not for David Geffen, we wouldn't have had a Prop 8 case. When we were trying to figure out how to file and fund the case, Rob and Michele Reiner and I met with David Geffen and he immediately wrote [a] $1.5 million [check], and called Steve Bing and asked him to raise the other $1.5 million.”

The Supreme Court has been asked to review the case.
