The Department of Transportation’s inspector general has opened an audit into the relocation of the Federal Aviation Administration’s air traffic control facility responsible for flights approaching or departing Newark Liberty International Airport.

Transportation Secretary Sean Duffy requested the audit to see if the move had a role in communications and radar outages at the Newark airport this spring.

Staff are burnt out — and very concerned about safety and feel very strongly that those moved to Philadelphia should come back to this facility,” Gillen said.

Federal audit ordered to review FAA's controversial transfer of air traffic controllers from New York to Philadelphia.
