'Duffy Lied': Air Traffic Controllers Refute Trump Transportation Secretary's Ground Stop Explanation

Air traffic controllers are disputing Transportation Secretary Sean Duffy’s explanation for Friday’s nationwide flight ground stop, which disrupted travel for an estimated 1.5 million people. Duffy said overloaded switches and routers caused inconsistent radar and communications data, forcing the system to shut down. Washington Examiner reporter Anna Giaritelli said controllers she contacted questioned that account, including the timing of the equipment changes cited by the administration.
