Transportation Security Administration union leaders have criticized President Donald Trump's decision to send Immigration and Customs Enforcement officers to selected airports, calling it an "insult" and a "waste of money". They argue that the move will not significantly impact the long security lines caused by the Department of Homeland Security shutdown. The union also expressed anger that ICE officers are being paid for their services, while TSA officers are still working without salaries. The pay crisis remains the central issue for about 50,000 to 61,000 TSA employees working without pay.
