WASHINGTON – No Democratic attorney general in a state that prohibits same-sex couples from marrying has signed onto a legal filing asking the Supreme Court to uphold California’s constitutional ban on gay marriage.

No Republican attorney general is asking the high court to rule in favor of marriage equality.

The Republican leadership in the House of Representatives, supported by 10 GOP senators, is spearheading the defense of the federal law that prevents legally married gay couples from collecting a range of federal benefits otherwise available to married couples.
