Current Transportation Secretary Sean Duffy criticized former Transportation Secretary Pete Buttigieg for mismanagement, accusing him of failing to address the air traffic controller shortage and upgrade the outdated air traffic control system. Duffy responded to Buttigieg's inquiry about FAA personnel layoffs, stating that less than 400 probationary employees were let go and no critical safety personnel were affected. He alleged that Buttigieg used the Department of Transportation as a slush fund for environmental initiatives and claimed that over 90% of the workforce worked from home under Buttigieg's leadership. Buttigieg challenged Duffy's claims and sought more specifics, while Duffy mentioned SpaceX engineers visiting the Air Traffic Control System Command Center to enhance air travel safety.
