Texas Attorney General Ken Paxton wants an investigation opened into whether San Antonio's move to keep Chick-fil-A out of the city's airport amounts to religious discrimination.

San Antonio City Council members voted to exclude the fast-food chain from the airport's concessions lineup last week because of the company's "legacy of anti-LGBTQ behavior," according to KTSA News.

"Everyone has a place here, and everyone should feel welcome when they walk through our airport," councilman Robert Trevino said. The city is in the middle of refreshing the airport's food offerings by 2020.

In a statement to Fox News, Chick-fil-A said it's open to more discussions with the city.

"It's unfortunate that mischaracterizations of our brand have led to decisions like this. ... The sole focus of the Chick-fil-A Foundation is to support causes focused on youth and education. We are proud of the positive impact we are making in communities across America and have been transparent about our giving on our web site," the company said.

While city leaders saw an issue with discrimination and equality, the attorney general's office sees the move as an infringement on religious beliefs.

Paxton sent a letter to the city, as well as to U.S. Transportation Secretary Elaine Chao, requesting an investigation into whether council's actions violated federal law.

"The City of San Antonio's decision to exclude a respected vendor based on the religious beliefs associated with that company and its owners is the opposite of tolerance," Paxton's statement read.

San Antonio Mayor Ron Nirenburg said the city attorney's office was reviewing the letter. Meanwhile, U.S. Sen. Ted Cruz took to Twitter to call the prohibition of Chick-fil-A from the airport "ridiculous."

The details of this story are even worse. San Antonio City Council voted to ban ⁦@ChickfilA⁩ from the airport bc the company gave to...the Fellowship of Christian Athletes & the Salvation Army?!? That’s ridiculous. And not Texas. #LeftistIntolerance https://t.co/ApTnlpS2E0 — Ted Cruz (@tedcruz) March 23, 2019

Texas Values, a nonprofit organization that said it's dedicated to faith, family and freedom, described the move as targeting Christian businesses, according to News 4 San Antonio.

"Local governments targeting and banning private Christian businesses like Chick-Fil-A is a hostility to religion that Texans will not stand for," the organization said. "I thought Texas was 'open for business.' I guess that applies everywhere in Texas except for San Antonio, where the government demands that you renounce your religious beliefs."

The ban was part of a seven-year concession agreement with Paradies Lagardère that the city estimates will generate at least $2.1 million annually for the airport.

Chick-fil-A is a frequent target of LGBTQ organizations because of the company's late founder, S. Truett Cathy, who was a devout Southern Baptist. The fast-food chain is famously not open on Sundays.

Recent scrutiny came when ThinkProgress reported that Chick-fil-A donated $1.8 million to groups that it said discriminate against the LGBTQ community. It cited donations to the Fellowship of Christian Athletes and Salvation Army as examples.
