A backlash against passage of an Indiana bill that supporters say seeks to protect religious freedom but which critics say targets the LGBT community continues to grow.

Indiana Governor Mike Pence, a Republican, has been under fire since he signed the bill on Thursday. The measure seeks to prohibit any state and local laws that “substantially burden” a person's ability to follow his or her religious beliefs and defines a “person” to include a business or association.

A photo of the private signing ceremony which features Pence surrounded by several anti-gay activists surfaced over the weekend, fanning the debate over the bill's purpose.

One of the men who attended the ceremony was Eric Miller of Advance America. Miller has stated that the bill will “protect those who oppose gay marriage.”

During an appearance on ABC's This Week, Pence refused to say whether discrimination against gays should be legal, insisting that “it doesn't have anything to do with this law.”

On Monday, Republican lawmakers said they would look at options to ensure that the law does not lead to discrimination, though they would not commit to adding sexual orientation and gender identity as protected classes to Indiana's civil rights laws.

Earlier this month, a similar measure cleared the Republican-controlled Georgia Senate, but was shelved in the House after a Republican member added language that prohibited discrimination.

On Monday, North Carolina Governor Pat McCrory, a Republican, announced he would not sign a religious freedom bill advancing in the General Assembly that would exempt court officials from marrying gay couples.

“I don't think you should have an exception or a carve-out when you swore an oath to the Constitution of North Carolina or to the Constitution of the United States of America,” McCrory said. “Even if there are things in the constitution that I disagree with that are upheld by the courts.”

Arkansas Republican Governor Asa Hutchinson, on the other hand, has pledged his signature to a bill similar to Indiana's.
