WASHINGTON (AP) — San Antonio International Airport is not among the airports where federal immigration agents will be deployed under President Donald Trump’s latest plan to ease long security lines during the ongoing government shutdown.

Trump announced that Immigration and Customs Enforcement agents would be sent to some U.S. airports to assist the Transportation Security Administration with duties like checking IDs and monitoring exit lanes as staffing shortages worsen.

The move comes as TSA officers continue working without pay, leading to hundreds of resignations and long wait times at security checkpoints nationwide.

However, neither San Antonio nor Austin made the list of airports expected to receive ICE support.

At least three Texas airports are expected to see the additional personnel: Dallas-Fort Worth International Airport and both major airports in Houston.

Sen. Ted Cruz weighed in on social media, echoing the Republican criticism of Democrats for the shutdown. “If you’re stuck at an airport, if you’re waiting two, three, four hours, it is ridiculous. The reason it is happening is the Democrats have voted not to fund TSA,” he said.

His comments come as more than 400 TSA workers have quit since the shutdown began, and Democrats have blocked DHS funding over demands for reforms to ICE and Customs and Border Protection.

Hundreds of thousands of homeland security workers, including from the TSA, U.S. Secret Service and Coast Guard, have worked without pay since Congress failed to renew DHS funding last month.

“Bad idea,” said Sen. Lisa Murkowski, R-Alaska, about the new airport security plan, which Trump said would start Monday.

“What we need to do is, we need to get the DHS issues resolved, we need to get the TSA agents paid,” she told reporters at the Capitol, where the Senate held a rare weekend session. “Do you really want to have even additional tensions on top of what we are already facing?”

Senators advanced the nomination of Sen. Markwayne Mullin, R-Okla., to be Trump’s next homeland security secretary by a largely party-line vote, 54-37, with two Democrats joining most Republicans. A vote on the confirmation could come as early as Monday. Mullin has tried to make the case that he would be a steady hand after the tumultuous tenure of Kristi Noem, Trump’s first DHS secretary.

Border czar heads up airport security effort

White House border czar Tom Homan, named by Trump to lead the new airport security effort, has also been meeting with a bipartisan group of senators over the partial shutdown. While he characterized those sessions as “good conversations,” he said they were “not at a point yet where we’re in total agreement.”

Meanwhile, Homan said in Sunday news show interviews that the increased role of U.S. Immigration and Customs Enforcement at airports — its specific duties and numbers — was subject to discussions with the leadership of TSA and ICE. DHS spokeswoman Lauren Bis said “hundreds” of ICE officers would be deployed, but she would not disclose the airports where they would go, citing security reasons.

“It’s a work in progress,” Homan said. The priority, he said, was “the large airports where there’s a long wait, like three hours.”

Atlanta Mayor Andre Dickens issued a statement Sunday night saying officers from ICE and Homeland Security Investigations would be deployed to the Hartsfield-Jackson Atlanta International Airport starting Monday morning.

At the airport on Sunday, some travelers waited in line for nearly six hours at the main security checkpoint, where only two TSA agents were on hand midafternoon to check IDs. Many missed their flights and scrambled to book later flights or add themselves to standby lists that were already dozens of names long.

Dickens said all federal personnel would report to TSA and be assigned tasks such as line management and crowd control. “Federal officials have indicated that this deployment is not intended to conduct immigration enforcement activities,” his statement said.

Homan said immigration officers, as an example, could cover exits currently monitored by TSA agents, freeing them to work screening lines. Another option, he said, was having ICE agents check identification before people enter screenings areas.

“We’re going to be a force multiplier,” Homan said, while also acknowledging there were limits.

“I don’t see an ICE agent looking at an X-ray machine, because we’re not trained in that,” he said. He pledged to have “a plan by the end of today, where we’re sending — what airports we’re starting with and where we’re sending them.”

But Everett Kelley, president of the American Federation of Government Employees, which represents more than 50,000 TSA employees, condemned Trump’s plan, saying in a statement that ICE agents are not trained or certified in aviation security.

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

Budget talks stall as airport worries worsen

Democrats have said they are willing to fund TSA and most other parts of DHS as they press for changes to immigration operations after the deaths of two U.S. citizens at the hands of federal agents in Minneapolis during an immigration enforcement operation. ICE officers are largely being paid during the partial shutdown, thanks to an influx of cash from Trump’s big tax breaks bill last year.

“There are lots of ideas swirling right now,” said Senate Majority Leader John Thune, R-S.D. “The good news in all that is people realizing this has to get fixed, it has to get solved.”

As budget talks stayed behind closed doors Sunday, senators said they had few details of which airports or how many immigration officers were being dispatched. Some welcomed the effort.

“I don’t think it can hurt,” said Sen. Mike Rounds, R-S.D. “They can help relieve some of the pressure.”

Trump said in a social media post that on Monday, “ICE will be going to airports to help our wonderful TSA Agents who have stayed on the job” despite the partial government shutdown. He further criticized Democrats.

Travelers at some airports worried about reaching their gates Sunday.

At Atlanta’s airport, lines wrapped from one end of the airport to the other.

The scene appeared more chaotic at John F. Kennedy International Airport in New York. Large crowds of anxious travelers piled toward security checkpoints, and TSA staff shouted through megaphones to tell people not to push one another.

For Transportation Secretary Sean Duffy, one concern is the uncertainty that passengers are facing over possible wait times at any airport on any given day.

“Do I have to come an hour and a half early? Do I have to come four hours early? They don’t know until the day of or the afternoon of their flight,” he said. “So if we can alleviate that, again, the president wants to take away that leverage point for Democrats and make travel easier for the American people.”

Homan appeared on CNN’s “State of the Union” and “Fox News Sunday,” while Duffy was interviewed on ABC’s “This Week.’ ___
