Texas Gov. Greg Abbott formally referred Dallas-Fort Worth and Houston’s George Bush Intercontinental airports to the U.S. Department of Justice on August 21, arguing that ablution facilities for Muslim travelers violate federal anti-discrimination law at government-owned airports. The DOJ referral followed an August 14 action in which Abbott threatened state grant revocations and referred both airports to the Transportation Department — moves that compelled DFW to cancel expansion plans within hours.

Abbott’s August 21 letter to Attorney General Todd Blanche argued the washing stations “single out one subset of the population for special treatment based on religion” and compared them to “white-only bathrooms.” The letter invoked federal grant compliance requirements under the FAA’s Airport Improvement Program, noting that airports receiving federal funds “are subject to conditions that require full compliance with laws prohibiting religious discrimination.” Both airports installed ablution facilities — DFW in 2019, Houston in February 2024 — and operated them without legal challenge until Abbott’s August intervention.

The governor’s office directed a review of all state grants to Texas airport operators on August 14, warning of “revocation of active state grant funds and the denial of any future grants” for airports found in violation of anti-discrimination law. That same day, Abbott referred both airports to Transportation Secretary Sean Duffy for federal investigation. DFW announced that evening it was scrapping plans for two additional ablution stations in Terminal D, stating the project “would not deliver the originally anticipated operational benefits.”

Facilities Include Islamic Religious Items

The facilities at issue are low-basin washing stations used for wudu, the ritual cleansing Muslims perform before prayer. DFW installed two ablution stations adjacent to its Terminal D Interfaith Chapel in 2019. Houston opened its Terminal D ablution room in February 2024, connected to a prayer room furnished with “copies of the Quran, prayer rugs, prayer beads and a turbah” — items specific to Islamic religious practice.

Houston Mayor John Whitmire defended the facility as open to all travelers regardless of faith, noting it was “paid for by fees charged to the international airlines” serving Middle East routes. Emirates, Qatar Airways, and Turkish Airlines carried approximately 366,000 passengers from IAH Terminal D in 2025, accounting for 22 percent of international departures. Whitmire’s statement noted that “prior to the development of the dedicated washing station, travelers often used restroom sinks and other public water facilities for personal washing needs.”

Abbott’s August 14 letter to DFW CEO Christopher McLaughlin stated he was “unaware of either airport installing standalone facilities to meet the particular needs of the many other religious groups represented across Texas.” The letter concluded that “engaging in these discriminatory practices will subject any organizations found to be in violation to the withdrawal of grant funding and other enforcement actions.”

Funding Source Questions Preceded Cancellation

The proposed DFW expansion drew scrutiny after an initial Texas Department of Licensing and Regulation filing listed the project cost at $300,000 and marked it “privately funded.” State Sen. Tan Parker, chair of the Senate Transportation Committee, sent DFW a list of questions on August 13 asking who provided the private donation and how it was accepted.

The filing was revised to show $115,000 and changed the funding classification to “public funds, public land.” DFW called it an “administrative error” by the design firm preparing the permit. The airport said it does not use taxpayer dollars for operations, relying instead on parking and concession revenue. Neither DFW nor Houston has disclosed the original funding source for their existing ablution facilities installed in 2019 and 2024.

Grant Leverage as Policy Enforcement Mechanism

The airport action represents Abbott’s deployment of grant compliance authority to enforce contested policy positions. In May, Abbott threatened to revoke $530,000 in state grants unless Grand Prairie canceled an Eid celebration at a city-owned water park. The event’s initial flyer read “Muslims only,” which Abbott argued violated House Bill 4211, Texas legislation banning residential and public facilities from excluding non-Muslims. Grand Prairie canceled the event.

In October 2025, Abbott ordered the Texas Department of Transportation to withhold funding from cities that refused to remove rainbow crosswalks, calling them unauthorized markings conveying “political ideologies” on public roadways. Transportation Secretary Duffy had sent governors a letter in July 2025 urging removal of “political messaging” from roads and threatening federal funding cuts for non-compliance.

The grant-leverage strategy escalates enforcement beyond legislative authority. Airports operate under dual federal-state jurisdiction, with the FAA exercising primary control over terminal security and access through its Airport Improvement Program. Airports accepting AIP grants agree to 39 grant assurances, including civil rights compliance requirements. Abbott’s letters invoked these federal conditions to justify state and federal enforcement action.

DOJ Referral Seeks Federal Civil Rights Investigation

Abbott’s August 21 DOJ letter argued the facilities are “clearly purposed to benefit the Muslim population alone” and are “not comparable to any existing interfaith chapels, which are open and available to all.” He wrote that “airports can no more offer Muslim-only bathroom spaces than they can maintain white-only bathrooms” and requested the Justice Department “immediately review these discriminatory facilities at DFW and IAH and take appropriate corrective action.”

The Council on American-Islamic Relations called Abbott’s action an “anti-Muslim political stunt” and argued the facilities are “universally-accessible” and comparable to interfaith chapels. CAIR is currently suing Abbott over his November 2025 proclamation designating the organization as a “Foreign Terrorist Organization” under Texas law.

Neither the Justice Department nor the Transportation Department has publicly responded to Abbott’s referrals. Both airports continue operating their existing ablution facilities. DFW has not announced plans to remove its two stations installed in 2019.
