Indiana's Republican legislative leaders said Monday they're working on adding language to a new state law to make it clear that it doesn't allow discrimination against gays and lesbians.

The move comes amid widespread outcry over the measure that prohibits state laws that "substantially burden" a person's ability to follow his or her religious beliefs. The definition of "person" includes religious institutions, businesses and associations.

Businesses and organizations across the country have canceled future travel to Indiana, tabled expansion plans or criticized the legislation. Opponents have taken to social media with the hashtag #boycottindiana.

House Speaker Brian Bosma and Senate President Pro Tem David Long said during Monday's news conference that similar laws exist across the country and have not generated the backlash that Indiana has seen. Bosma blamed the reaction on a "mischaracterization" of the law by both opponents and some supporters.

"What we had hoped for with the bill was a message of inclusion, inclusion of all religious beliefs," Bosma said. "What instead has come out as a message of exclusion, and that was not the intent."

Indiana Gov. Mike Pence signed the measure last week and defended it during a television appearance Sunday but did not directly answer questions about whether it allowed discrimination against gays and lesbians.

Long stressed the new law is based on the federal Religious Freedom Restoration Act of 1993 that has been upheld by courts.

"This law does not and will not be allowed to discriminate against anyone," Long said.

The furor over the Indiana law stems in part from the fact that the state's civil rights laws don't ban discrimination based on sexual orientation.

Long and Bosma did not appear eager to add that language into the measure, noting that it is a big policy decision and that only four weeks remain in this year's legislative session.

Some national gay-rights groups say the law allows lawmakers in Indiana and several other states where similar bills have been proposed this year to sanction discrimination as the nation's highest court prepares to mull the gay marriage question.

Supporters of the law insist the law will keep the government from compelling people to provide services they find objectionable on religious grounds. Arkansas is poised to follow in Indiana's footsteps, as Republican Gov. Asa Hutchinson has said he'll sign a measure moving through the state's Legislature.
