With near-daily TV appearances, the transportation secretary has emerged as the face of the Trump administration amid the shutdown.

Some admitted they would have postponed trips had they known how severely the shutdown would impact air traffic controllers. Many, however, had booked flights months in advance.

House Minority Leader Hakeem Jeffries wants information about the Trump administration’s layoffs and Federal Aviation Administration changes and that have been underway even before the shutdown.

Phoenix Sky Harbor passengers arrive hours early as government shutdown forces FAA to cut flights 10%. Unpaid air traffic controllers work 37 days without pay, creating staffing shortages and travel delays.

As the nation’s airlines are directed to cut flights to deal with what Transportation Secretary Sean Duffy says are concerns over aviation safety, travelers are becoming fed up.
