The partial shutdown of the Department of Homeland Security, now in its sixth week, reached a flashpoint over the weekend as security wait times at major airports surged to crisis levels. Hartsfield-Jackson Atlanta International Airport — the nation's busiest — saw travelers endure security lines stretching to nine hours on Sunday, with a 41.5 percent TSA officer call-out rate as unpaid workers stayed home in growing numbers. New Orleans reported nearly 42 percent absenteeism; JFK was at 37.4 percent. The DHS estimated that more than 400 TSA officers have quit since the shutdown began in mid-February, when Congress deadlocked over the administration's demand to fund ICE operations alongside the rest of the department. Some 50,000 TSA officers nationwide continue working without pay, with a second missed paycheck threatening to worsen the situation further.

In response, President Trump announced Monday that ICE agents would be deployed to airports to assist with security lines. Border Czar Tom Homan confirmed agents would be "at airports tomorrow helping TSA move those lines along." By Monday morning, at least 50 ICE personnel per shift were positioned at 13 airports, per NBC News, stationed at security entrances and exits to manage crowd flow and ID verification — but not performing X-ray or magnetometer screening, which requires TSA certification. Fox News reported the deployment under the headline "Mask-free ICE agents begin patrolling US airports" — Trump specifically asked agents not to wear masks at airports while assisting with lines, though he noted he remains a "big proponent" of masks during immigration enforcement operations. He also warned that National Guard deployment was an option if conditions did not improve.

The Trump administration simultaneously rejected a proposal by Senate Majority Leader John Thune that would have funded all DHS operations except ICE through appropriations — with ICE handled separately through a Republican reconciliation bill. Trump demanded that Democrats first agree to pass the SAVE America Act — his voting-legislation priority — before any DHS deal, effectively tying two unrelated policy disputes together. NBC News reported this left Republicans in a political bind: unable to end the shutdown unilaterally while holding their members together. Democrats have made eight separate attempts to pass stand-alone TSA funding through unanimous consent, all blocked by Republicans.

The ACLU told NBC News that "families traveling to see loved ones should not have to deal with ICE agents who likely have no training or experience with the mission of airport security." Illinois Governor JB Pritzker's office called the ICE deployment counterproductive, arguing it addressed a symptom — long lines — while ignoring the cause: unpaid workers calling out or resigning. The U.S. Travel Association called on Congress to act urgently, noting the irony that 171 million passengers are projected to travel during March and April — a record season — while lawmakers prepared for recess. Transportation Secretary Sean Duffy stated that ICE agents "know how to run the X-ray machines," a claim TSA union officials immediately disputed, saying ICE is "not trained or certified in aviation security."
