"I am pleased to announce that I am directing our GREAT Secretary of Transportation, Sean Duffy, to be Interim Administrator of NASA," Trump posted to Truth Social. "He will be a fantastic leader of the ever more important Space Agency, even if only for a short period of time."

The president praised Duffy’s performance at the Department of Transportation, calling his tenure "TREMENDOUS," and sharing his work on air traffic control modernization and infrastructure revival.

Isaacman, a billionaire private astronaut and longtime associate of Elon Musk, was nominated by Trump in December 2024 but faced mounting scrutiny over ties to Musk and SpaceX, which some officials viewed as a conflict of interest.According to The Associated Press, Trump said the decision to pull Isaacman’s name came after a "thorough review of prior associations" and growing concern over "corporate entanglements."

NASA has increasingly factored into the Trump administration’s national defense, innovation, and economic agenda. Trump has long emphasized the strategic importance of space, launching the Space Force during his first term.
