In recent weeks, a series of pointed online exchanges have unfolded between prominent political figures regarding the oversight of government spending and the future of the nation’s transportation infrastructure.

A member of President Donald Trump’s administration engaged in a public spat with former Secretary of State Hillary Clinton about the work undertaken by DOGE—an entity tasked with using innovative technology to identify wasteful spending at USAID. At the center of this debate is DOGE’s role under the leadership of Department of Government Efficiency boss Elon Musk. The controversy escalated when Transportation Secretary Sean Duffy responded to an online jab from Clinton, who criticized the department’s ability to manage the aviation systems upgrade in the wake of recent deadly plane crashes.
