WASHINGTON (AP) — The Transportation Security Administration (TSA) is facing unprecedented wait times for travelers, with concerns growing as the funding stalemate in Congress continues. Acting TSA head Ha Nguyen McNeill testified before Congress warning that ongoing financial strain on airport workers has led to dire situations where employees are unable to meet basic living expenses.

Amidst the government's shutdown which is now on its 40th day, McNeill reported that numerous airports are seeing a significant increase in callout rates among staff, leaving travel security vulnerable as over 480 officers have resigned during this period.

The crisis highlights the struggle workers face, including turned-away calls for assistance, sleeping in their cars, and even selling blood plasma to cover expenses. As the TSA manages only a fraction of its normal operations, the potential for security lapses grows, raising alarms among lawmakers.

Proposals to resolve the funding issue are hitting walls, with neither side willing to concede on key immigration enforcement strategies that have drawn bipartisan scrutiny. Senate Democratic leader Chuck Schumer emphasized the need for actual reforms, especially after incidents involving federal officers during protests.

Transportation officials, such as Jim Szczesniak, the aviation director for Houston's airport, have cautioned that growing lines could extend to four hours or more if the impasse continues, stressing that the current environment is unsustainable for both travelers and authorities alike.

Compounding these issues, FEMA's disaster relief funding is reportedly nearing depletion, further endangering emergency relief efforts across the nation.
