During an interview with CBS aired on Thursday's edition of "CBS Evening News," Transportation Secretary Pete Buttigieg responded to a question on air traffic control staffing issues and why they haven't been resolved after the Department of Transportation sharply criticized airlines for their issues with staffing by stating that the agency is hiring people and is "going to own anything that's under our control." But air traffic control is only "5% of the issue" and "a much greater share of the delays and cancellations" are the fault of the airlines. He also acknowledged that the airlines have improved since a year ago.
