March 23 (UPI) — President Donald Trump’s border czar Tom Homan has confirmed that Immigration and Customs Enforcement agents will be deployed to U.S. airports starting Monday, despite strong opposition from unions and Democrats.

Homan told CNN’s State of the Union on Sunday that he was working on the plan’s execution with acting ICE Director Todd Lyons and Transportation Security Administration Administrator Ha Nguyen McNeill.

“So, we’ll put together a plan today and we’ll execute it tomorrow,” he said.

On Sunday, Trump threatened to send ICE agents to U.S. airports over a protracted fight with Democrats over Department of Homeland Security funding.

Funding for DHS lapsed Jan. 31 after Congress failed to pass legislation to keep the department open, with Democrats are demanding reforms in response to federal immigration agents deploying aggressive tactics during the Trump administration’s immigration crackdown.

The partial shutdown is affecting the TSA, which is under the DHS. Airports are reporting long lines and congestion due to a shortage in TSA staff, who haven’t been paid since DHS funding ran out.

Trump threatened on his Truth Social platform that ICE will perform security at airports where they will arrest undocumented migrants, raising questions about whether the agents are being sent only to relieve pressure on TSA or to carry out immigration enforcement at major travel hubs.

Homan on Sunday sought to frame the move as a way to alleviate congestion and move long lines of travelers though security.

Asked if ICE had the specialized training to inspect bags and passengers, Homan said he doesn’t expect the immigration agents to be ‘looking at an X-ray machine, because we’re not trained in that.”

“But there are certain parts of security that TSA is doing that we can move them from those jobs, and put them in the specialized jobs to help those lines,” he said, adding that discussions with the TSA concerning what security roles ICE agents would perform were ongoing.

“We will have a plan by the end of today … what airports we’re staring with and where we’re sending them,” he said, suggesting that the worst affected airport will be given priority.

“So it’s a work in progress, but we will be at airports tomorrow helping TSA move those lines along.”

He also confirmed that ICE agents will perform immigration enforcement at the airport, underscoring that their deployment is mainly to aid TSA.

Republicans have attempted to characterize the shutdown as Democrats prioritizing undocumented immigrants over airport security, while the Democrats have blamed Republicans for blocking more than half a dozen attempts to pass legislation to fund the TSA, including on Saturday. The GOP lawmakers say they want to fund the entirety of the DHS.

“Instead of sending ICE agents to harass travelers at airports, why don’t Republicans get their act together and agree to pay TSA workers like we’ve asked them to SEVEN TIMES now?” Senate Minority Leader Chuck Schumer, D-N.Y., said in a statement on X on Sunday.

Vice President JD Vance accused Schumer of continuing “to hold TSA funding hostage.”

“Thankfully, ICE will bring sanity to our airports starting tomorrow, but it’s far past time for Democrats to fund DHS,” he said.

Following Homan’s interview, Rep. Dan Goldman, D-N.Y., accused the Trump administration of using ICE “to strike fear and terror on our airports.”

“Mr. President, it’s pretty simple: if you want TSA agents to get paid (as they should), then pass the Democrats’ bill to fund TSA,” he said on X. “No need for your out-of-control paramilitary to do yet another thing they aren’t trained to do.”

Hartsfield-Jackson Atlanta International Airport has been informed it is among those where ICE agents will be deployed Monday, Atlanta Mayor Andre Dickens said in a statement.

The agents will report to the TSA and will be assigned to line management and crowd control within domestic terminals, he said, adding that federal officials have indicated that they are not intended to conduct immigration enforcement activities.

“Our administration remains hopeful the Federal Government can soon find a way to fully fund TSA and pay their employees to resume standard operations at Hartsfield-Jackson Atlanta International Airport — and all airpots we connect to,” he said.

The deployment of ICE agents is also being lambasted by the American Federation of Government Employees, the largest government worker union in the United States.

It accused the Trump administration of sending ICE agents to do the jobs of the more than 50,000 TSA employees who have worked without pay for more than five weeks.

It also expressed worry that the ICE agents will be undertrained for what they may be required to do, arguing that stationing them at security checkpoints will create security risks.

“Our members at TSA have been showing up every day, without a paycheck, because they believe in the mission of keeping the flying public safe,” AFGE National President Everett Kelley said in a statement.

“They deserve to be paid, not replaced by untrained, armed agents who have shown how dangerous they can be.”

The leaders of several flight attendant unions also criticized the Trump administration on Sunday for using the TSA and frontline security officers “as pawns in this dangerous game,” stating that the DHS can use its billions of dollars in discretionary funding to pay them.

“This latest threat of ICE invasion at the airports is another distraction from solutions that protect Americans,” the Association of Flight Attendants-CWA, the Association of Professional Flight Attendants, International Brotherhood of Teamsters Local 135 and the International Association of Machinists and Aerospace Workers said in a joint statement.
