New York Governor Kathy Hochul on Saturday called for Sean Duffy to resign or be removed following a nationwide failure of aviation radar and communications systems. The governor’s office issued the statement a day after the airspace halt canceled thousands of flights and stranded travelers across the country.

Hochul said more than 3,500 planes were in the air when the systems faltered. She noted that no lives were lost during the incident.

The governor claimed that serious lapses in the aviation system, including chronic air traffic controller shortages and repeated communications breakdowns, have become a pattern on Duffy’s watch. She accused Duffy of being more focused on “starring in his own reality show than addressing the crisis at his agency.”

With millions of Americans preparing for holiday travel, Hochul said families deserve answers and confidence in the safety of the skies. She urged Congress to begin a comprehensive inquiry into the incident to find out what caused the failure and prevent future occurrences.

Hochul stated that Duffy must resign immediately, or President Trump must remove him.
