U.S. airports could face a new wave of long security lines as early as May after ​the nation’s homeland security chief said on Tuesday that he will run ‌out of money to pay for 50,000 workers due to a partial government shutdown.

President Donald Trump in late March directed DHS to use emergency funds to pay Transportation Security Administration workers who had gone without paychecks ​for about six weeks, causing disruptions at U.S. airports. Homeland Security Secretary Markwayne ​Mullin told “Fox and Friends” on Tuesday that the money would run out ⁠by early May.
