TOPEKA, Kan. (AP) — Republican Governor Sam Brownback says he's considering proposing a new religious objections law for Kansas following the U.S. Supreme Court's decision legalizing gay marriage across the nation. Brownback on Thursday also defended the state's refusal so far to allow gay and lesbian spouses to change their last names on driver's licenses or to file joint income tax returns. The governor said his administration wants to make sure such changes are handled correctly. Brownback has been a strong supporter of the state's ban on same-sex marriage that was reinforced by a 2005 amendment to the Kansas Constitution. The governor said religious liberties need to be protected. As for legislation next year, he said, "We're looking at that." Gay-rights leader Tom Witt said Brownback is defying the high court ruling.
