Supreme Court justices heard arguments today for and against California's 2008 ban on same-sex marriage known as Proposition 8.
The justices have the power to make same-sex marriage the law of the land. Currently, it's only the law in nine states and Washington D.C.
Some justices seemed wary of issuing a broad ruling.
"This was a deeply divided Supreme Court, and a court that seemed almost to be groping for an answer here," said CNN Senior Legal Analyst Jeffrey Toobin after following 80 minutes of arguments.
