The Transportation Security Administration (TSA) has experienced staffing shortages at Houston's Hobby Airport and other airports, impacting over 2 million spring break travelers. Travelers are waiting two hours to get through TSA, compared to three hours earlier on Sunday and earlier Monday, leading to several flight delays. TSA agents are working without pay after Congress voted against funding the Department of Homeland Security over immigration policies. The shutdown is affecting airports nationwide, particularly in New Orleans and Washington, as Democrats continue to hold up DHS funding.
