Indiana Republicans pledged on Monday to clarify a new "religious freedom" law, while similar proposals stalled in Georgia and North Carolina after businesses and activists said such measures could be used to discriminate against gays.

Arkansas lawmakers, however, signaled they would move forward with their own bill, even after Indiana was rebuked by companies and executives, including Wal-Mart Stores Inc., Apple Inc. CEO Tim Cook, and Eli Lilly and Co.

Indiana's law, signed by Gov. Mike Pence last week, was perceived as going further than those passed in 19 other states, giving businesses a right to refuse services on religious grounds.
