A Transportation Security Administration official has warned that small U.S. airports could be forced to close if the federal government shutdown continues, as TSA officers working without pay have increasingly called out of work or resigned from their positions.

The shutdown, which has lasted more than a month, has left thousands of TSA officers working without receiving paychecks. This situation has led to a growing number of absences and resignations among airport security personnel across the country.

Smaller airports appear to be particularly vulnerable to staffing shortages, as they typically operate with fewer TSA officers than major metropolitan airports. The potential closure of these facilities could significantly impact air travel in affected communities.

TSA officers are considered essential personnel and are required to work during government shutdowns, but they do not receive pay until Congress passes funding legislation. The extended duration of the current shutdown has created financial hardship for many federal workers.

The warning comes as the shutdown continues with no immediate resolution in sight, raising concerns about the broader impacts on aviation security and airport operations nationwide.
