Indiana’s governor is expected to sign into law a religious objections bill that some convention organizers and business leaders are opposing amid concern it could allow discrimination against gay people.

Republican Mike Pence plans to sign the measure Thursday in a private ceremony. It would make Indiana the first state to enact such a change this year among about a dozen where such proposals have been introduced. The measure would prohibit state and local laws that “substantially burden” the ability of people, businesses and associations to follow their religious beliefs.

Organizers of a 50,000-person gamers’ convention and a large gathering of the Christian Church (Disciples of Christ) sent letters to Pence this week saying they’re considering moving events from Indianapolis over the issue.
