U.S. Transportation Secretary Sean Duffy voiced sharp criticism on Thursday over the ongoing Democrat-led government shutdown, revealing that roughly 13,000 air traffic controllers are currently working without pay.

“They’re angry,” Duffy said during a press briefing. “They’re frustrated that [Democrats are] focused on paying for health care benefits for illegals as opposed to paying their paychecks.”

The remarks underscore growing tensions inside the Department of Transportation, where critical aviation safety personnel continue to report for duty despite lapsed federal funding. Officials warn that extended disruption could soon affect flight scheduling, safety oversight, and airport operations nationwide.

The shutdown, now entering its second week, stems from a budget standoff between House Republicans and Senate Democrats over a $1.5 trillion spending package. Republicans have demanded provisions prioritizing domestic payroll protection and border security funding, while Democrats insist on maintaining healthcare coverage for undocumented immigrants.

Secretary Duffy called on congressional leaders to “put American workers first” and restore funding to essential federal operations.

“We’re talking about men and women responsible for keeping the skies safe,” Duffy said. “They shouldn’t be caught in the middle of political games.”

The Federal Aviation Administration (FAA) confirmed that all air traffic control towers remain operational, though morale has plummeted among unpaid employees, many of whom have expressed frustration over mounting personal and financial strain.

With no agreement in sight, industry experts warn that prolonged inaction could delay air travel and further strain the nation’s aviation workforce — turning the shutdown into a broader test of political leadership and public patience.
