President Obama is considering urging the US supreme court to overturn California's ban on gay marriage.
Proposition 8 was voted by Californians in 2008 and overturned a state supreme court decision allowing gay marriage.
Twenty-nine other states have constitutional amendments banning gay marriage, while nine states and Washington, D.C., recognize same-sex marriage.
Obama told San Francisco’s KGO-TV that the government is considering filing an administration brief against proposition 8 in the supreme court.
