SAN DIEGO — The Trump administration said Sunday that ICE agents will begin handling some security duties at U.S. airports Monday amid an ongoing partial government shutdown that has sidelined many Transportation Security Administration officers, with border czar Tom Homan in charge of the effort.

Travelers were warned to expect delays. The San Diego County Regional Airport Authority issued a travel advisory Sunday for passengers traveling out of the city’s airport.

“Passengers traveling out of San Diego International Airport are encouraged to check their flight status before coming to SAN and plan to arrive at least two hours before their flight,” airport spokeswoman Nicole Hall said Sunday, the second day the airport was experiencing delays.

“Checkpoint wait times and flight scheduling are subject to the operations of our federal and airline partners. These operations are, at times, affected by the federal government shutdown.”

Hall said an influx of seasonal spring break travelers was also affecting wait times, which could take up to one hour during a “fluid situation.”

“We appreciate the ongoing commitment from TSA, FAA, and our partner airlines to maintain the safety and reliability of the national transportation system during this challenging time,” Hall said. “Our focus remains on ensuring a safe and efficient airport experience.”

Travelers to SAN were encouraged to plan ahead and arrive two hours before domestic flights and three hours prior to international departures.

Homan told CNN’s “State of the Union” on Sunday that the effort was about “helping TSA do their mission and get the American public through that airport as quick as they can while adhering to all the security guidelines and the protocols.”

“We’re simply there to help TSA do their job in areas that don’t need their specialized expertise, such as screening through the X-ray machine,” he said. “Not trained in that? We won’t do that. But there are roles we can play to release TSA officers from the non-significant roles, such as guarding an exit so they can get back to the scanning machines and move people quicker.”

Further details about the plan were expected later Sunday.

On Saturday, President Donald Trump said he would order ICE agents to assist with airport security if Congress did not immediately reach an agreement to fund TSA officers.

In a social media post, Trump said ICE agents could also be tasked with making immigration arrests at airports.

“If the radical left Democrats don’t immediately sign an agreement to let our country, in particular, our airports, be FREE and SAFE again, I will move our brilliant and patriotic ICE agents to the airports where they will do security like no one has ever seen before,” Trump wrote on Truth Social.

The proposal comes as a partial government shutdown has left roughly 50,000 TSA employees working without pay, contributing to increased absenteeism and staffing shortages at airports nationwide.

Administration officials said about 10% of TSA workers failed to report for duty on some recent days, compared to typical rates of less than 2%.
