ICE Agents Begin ID Checks in Airport Security Lines

The deployment of hundreds of Immigration and Customs Enforcement agents to America's busiest airports — ostensibly to ease a TSA staffing crisis caused by a 40-day government shutdown — has triggered a constitutional standoff over the boundaries between aviation security and immigration enforcement.

The Shutdown Behind the Deployment

The story begins not at an airport, but in Minneapolis. On January 24, 2026, Customs and Border Protection officers shot and killed Alex Pretti, a 37-year-old ICU nurse for the Department of Veterans Affairs, during an immigration enforcement operation [1]. Pretti had been filming federal agents and stood between an officer and a woman who had been pushed to the ground. Hours later, White House deputy chief of staff Stephen Miller called Pretti a "domestic terrorist" — a claim that was widely disputed and drew bipartisan condemnation [1].

The killing — coming weeks after the fatal shooting of another U.S. citizen, Renée Good, by an ICE agent on January 7 — catalyzed a congressional crisis [2]. Democrats refused to fund the Department of Homeland Security without reforms to immigration enforcement, demanding that agents carry judicial warrants before entering private property, verify citizenship before detaining individuals, wear body cameras, and remove face masks during operations [3]. Republicans countered that Democrats were holding national security hostage. The partial DHS shutdown began on February 14, 2026, and has now stretched past 40 days [4].

The immediate casualty: TSA officers stopped getting paid.

TSA in Crisis

By mid-March, more than 450 TSA officers had quit outright [5]. Those who remained faced mounting financial pressure — eviction notices, vehicle repossessions, and empty refrigerators. Some officers reported sleeping in their cars at airport parking lots to save gas money; others sold blood plasma to cover bills [5].

Callout rates spiked. On March 14, Houston Hobby International Airport recorded a single-day callout rate of 55% [6]. At JFK, Atlanta's Hartsfield-Jackson, and New Orleans' Louis Armstrong, more than a third of staff were absent on any given day [7]. On March 23, over 3,400 TSA officers — nearly 12% of the scheduled workforce — called out nationwide, the highest rate since the shutdown began [8].

The result: security wait times that the TSA administrator called "the highest in TSA history," with some passengers reporting waits exceeding six hours at Houston's George Bush Intercontinental Airport [8][9].

ICE Arrives at 13 Airports

On March 22, border czar Tom Homan announced that ICE would deploy agents to major airports as a "force multiplier" to support overwhelmed TSA operations [10]. By March 23, at least 50 ICE personnel per shift were stationed at each of 13 confirmed airports [7]:

• Chicago O'Hare International Airport
• Cleveland Hopkins International Airport
• Hartsfield-Jackson Atlanta International Airport
• Houston William P. Hobby Airport
• John F. Kennedy International Airport (New York)
• LaGuardia Airport (New York)
• Louis Armstrong New Orleans International Airport
• Luis Muñoz Marín International Airport (San Juan, Puerto Rico)
• Newark Liberty International Airport
• Philadelphia International Airport
• Phoenix Sky Harbor International Airport
• Pittsburgh International Airport
• Southwest Florida International Airport (Fort Myers)

DHS declined to release a complete list and indicated the number could grow [11]. Homan said ICE agents would man exits, check IDs before passengers enter screening areas, and perform crowd control — freeing TSA officers to return to screening duties [10]. Transportation Secretary Sean Duffy argued that ICE personnel operate "similar assets" at the southern border [10].

What ICE Agents Can — and Cannot — Do

The deployment created immediate confusion over the agents' actual role. Homan acknowledged that ICE officers lack training on X-ray machines and baggage screening: "I don't see an ICE agent looking at an X-ray machine, because we're not trained in that" [10]. AFGE President Everett Kelley, representing TSA workers, said the deployment "does not fill a gap — it creates one," noting that TSA officers spend months learning to detect explosives [12].

But ICE agents are not ordinary security personnel. Under the Immigration and Nationality Act, ICE officers have the authority to question any person about their immigration status and arrest anyone they believe is in the country unlawfully — anywhere in the United States [13]. That authority does not pause when they are assigned to airport crowd control.

Homan did not rule out immigration enforcement actions at airports, stating agents would be able to "arrest criminals going through the airport" and look for "human trafficking, sex trafficking, money smuggling" [14]. Former ICE Director John Sandweg warned: "If we start seeing ICE agents making immigration arrests...we're going to have chaos" [10].

That chaos may have already begun. On March 22, the day before formal deployment, two people were arrested by federal agents at San Francisco International Airport. DHS said both were in the country illegally and had a 2019 removal order [15]. Eyewitness video posted to social media showed plain-clothed agents declining to identify themselves while detaining individuals, including a child, past the security line at a terminal gate [15].

The ID Check Question

The most legally contentious element of the deployment is the ID verification role. TSA's standard document check — verifying that a passenger's identity matches their boarding pass — is conducted under aviation security authority established after September 11, 2001. Travelers who decline screening can simply leave the airport.

When ICE agents perform that same function, the legal framework shifts. An ICE officer checking IDs has the simultaneous authority to question immigration status, run names through immigration databases, and initiate enforcement actions [13]. Legal experts argue that travelers in a TSA security line have limited practical ability to walk away or decline questioning, raising Fourth Amendment concerns about whether such encounters constitute a seizure [16].

The ACLU has directly challenged the deployment. Director Naureen Shah stated: "Never in our history has a president deployed armed agents to the airport to inspire fear among families" [17]. The organization argues that embedding ICE at TSA lanes "heightens risks of racial profiling and unlawful questioning of citizens and lawful residents who appear foreign or speak accented English" [16].

The American Immigration Lawyers Association echoed these concerns, arguing that Congress created distinct roles for aviation security and immigration enforcement and that "collapsing those roles raises serious legal and constitutional concerns" [18].

Legal Challenges and Constitutional Questions

Several legal actions are underway. The ACLU has filed litigation challenging the expanded use of facial recognition, mobile fingerprint scanners, and real-time data sharing between TSA and ICE, contending these tools "were never publicly authorized for domestic dragnet immigration checks" [16]. A separate ACLU lawsuit in Minnesota targets ICE and CBP's "practice of suspicionless stops, warrantless arrests, and racial profiling" — litigation that predates the airport deployment but whose legal arguments apply directly to it [19].

The constitutional questions center on several provisions:

Fourth Amendment: Does an ICE agent checking IDs in a security line constitute an unreasonable search or seizure? TSA screening is permitted under the administrative search doctrine — a narrow exception allowing searches without individualized suspicion for specific regulatory purposes. Immigration enforcement does not fall under that doctrine [16].

Equal Protection: Are travelers being selected for additional questioning based on race, ethnicity, or national origin? No documentation on selection procedures has been made public, and DHS has not disclosed what training, if any, ICE agents received on avoiding profiling [16][17].

Due Process: Can travelers meaningfully decline an encounter with an armed federal agent while standing in a security line they cannot easily exit? Legal scholars argue the coercive environment of an airport checkpoint effectively eliminates the voluntariness that distinguishes a consensual encounter from a detention [16].

No court has yet issued a preliminary injunction against the airport deployment specifically, though several cases are in early stages [16].

The Overstay Data

The administration's implicit justification — that airports are a site of immigration violations — has some basis in data, though the numbers tell a more nuanced story.

DHS's most recent Entry/Exit Overstay Report, covering fiscal year 2024, found that 538,548 nonimmigrants overstayed their authorized period — an overall rate of 1.15% [20]. The vast majority of these overstays involved air travelers, since the biometric exit system primarily covers air and sea ports of entry.

Visa Waiver Program travelers — citizens of 41 allied nations who enter without a visa — had the lowest overstay rate at 0.43% across 18.8 million expected departures [20]. Non-Visa Waiver travelers (excluding Canada and Mexico) overstayed at a rate of 2.22%, and student and exchange visitors had the highest rate at 2.45% [20].

The compliance rate of over 98% raises a resource-allocation question: does stationing armed immigration agents at airport security lines represent an efficient use of enforcement resources compared to alternatives? The 2024 data shows that the overwhelming majority of air travelers comply with their visa terms.

The Effectiveness Question

Early evidence suggests the ICE deployment has done little to address the underlying crisis. A TSA union representative at one airport told CBS News: "I've seen them outside standing around, I don't know if they are doing anything" [8]. Wait times remained at four hours or longer at Houston's George Bush Intercontinental Airport a full day after deployment began [8].

The fundamental problem is mathematical: ICE agents cannot operate screening equipment, and screening is the bottleneck. An agency spokesperson acknowledged that agents were limited to crowd control, monitoring lines, and ID verification — tasks that do not increase the throughput of passengers through magnetometers and X-ray machines [7].

Alternative Approaches

Civil liberties organizations and immigration policy researchers have proposed several alternatives to checkpoint-based enforcement for addressing visa overstays.

The biometric exit system, which CBP has been expanding since a 2016 rule, uses facial recognition at departure gates to track whether nonimmigrants leave on time [21]. This data-driven approach identifies overstays after the fact and allows targeted follow-up rather than blanket screening of all travelers. A September 2025 CBP rule further expanded this system nationwide [21].

Congressional testimony has emphasized data-based approaches over officer discretion. As one witness told the House Judiciary Committee: "The analysis should be based on some data and some actual patterns of what have been prior experiences" rather than "hunches and presuppositions that are not very concrete" [22].

Other proposals include increased funding for immigration courts to reduce the case backlog that contributes to overstays, expanded use of electronic monitoring for individuals in removal proceedings, and employer verification systems that reduce the economic incentive to overstay [22].

The Broader Context

ICE has maintained a presence at some international airports for decades, primarily at customs and immigration checkpoints where international passengers arrive. The agency's Homeland Security Investigations division routinely works narcotics and trafficking cases at airports. What is new is the placement of Enforcement and Removal Operations agents in domestic security lines — spaces traditionally controlled exclusively by TSA [10][13].

The pace of ICE arrests nationally has accelerated sharply in 2026, topping 1,100 per day on average, compared to roughly 600 per day in spring 2025 [14]. The airport deployment occurs within this broader expansion of enforcement operations.

What Comes Next

The airport deployment is, at its core, a product of the DHS shutdown. If Congress reaches a funding agreement — negotiations remain ongoing but stalled as of March 26 [3][4] — TSA officers would be paid, callout rates would presumably fall, and the stated justification for ICE's presence would evaporate.

But the legal and political precedent may outlast the crisis that created it. The Trump administration has not committed to withdrawing ICE from airports once TSA is fully staffed. And the dual-use nature of the deployment — crowd control wrapped around immigration enforcement authority — has established a template that future administrations could invoke under different pretexts.

For the millions of travelers passing through these 13 airports, the immediate reality is this: armed federal immigration agents are now a fixture in domestic security lines, checking IDs under a legal authority far broader than the aviation security mandate that created those lines in the first place. Whether the Constitution permits that arrangement is a question the courts have only begun to consider.
