Texas Governor Greg Abbott, on Thursday, June 18, signed into law a bill designed to protect Texas businesses from discrimination on the basis of the business owner’s religious beliefs.

The legislation, known as the “Chick-fil-A bill,” is designed to prevent government entities from discriminating against businesses, organizations, or individuals on the basis of their religious affiliation. It was introduced to the Texas State Legislature in May, after the City of San Antonio denied fast food restaurant Chick-fil-A a contract to operate concessions for the city airport.

Gov. Abbott made the announcement Thursday evening via a post on Twitter. “Today I signed the Chick-fil-A law in Texas,” said Abbot. “No business should be discriminated against simply because its owners donate to a church, the Salvation army, or other religious organization. Texas protests religious liberty.”

Both the Texas House and Senate passed the bill on May 20.

Texas Attorney General Ken Paxton has also advised San Antonio’s Mayor Ron Nirenberg and members of San Antonio’s city council that he has opened an investigation surrounding the city’s decision to exclude Chick-fil-A from an airport concession contract that the city staff had recommended.

A member of San Antonio’s city counsel had reportedly opposed Chik-fil-A from receiving the concession contract, alleging that the restaurant chain has a “legacy of anti-LGBT behavior.” A second member of the council then supported a motion to deny awarding the contract, alleging that Chick-fil-A had become a “symbol of hate.”

Paxton has also requested that the United States Department of Transportation open an investigation into the City of San Antonio for potential violations of Transportation Department regulations and federal anti-discrimination laws.
