President Donald Trump has withdrawn the nomination of tech billionaire Jared Isaacman to lead NASA, citing a “thorough review of prior associations.”
The decision, announced late Saturday on Trump’s social media platform Truth Social, comes just days before Isaacman’s anticipated Senate confirmation vote.
“After a thorough review of prior associations, I am hereby withdrawing the nomination of Jared Isaacman to head NASA. I will soon announce a new Nominee who will be Mission aligned, and put America First in Space. Thank you for your attention to this matter!” Trump wrote.
Isaacman, 42, is the founder and CEO of Shift4 Payments and has been a prominent figure in private spaceflight, notably commanding SpaceX’s Inspiration4 mission and leading the Polaris Dawn mission, which included the first private spacewalk. His nomination in December 2024 received bipartisan support and endorsements from 28 former NASA astronauts.
While the White House did not elaborate on the specific reasons for the withdrawal, reports suggest that Isaacman’s past political donations to Democratic candidates and his close ties to SpaceX CEO Elon Musk may have influenced the decision. The move also follows Musk’s recent departure from his role in the Trump administration’s Department of Government Efficiency (DOGE).
In response to the withdrawal, Isaacman expressed gratitude for the nomination and support received.
“I am incredibly grateful to President Trump @POTUS, the Senate and all those who supported me throughout this journey. The past six months have been enlightening and, honestly, a bit thrilling. I have gained a much deeper appreciation for the complexities of government and the weight our political leaders carry,” Isaacman posted to X.
The Trump administration has indicated that a new nominee aligned with the “America First in Space” agenda will be announced soon. In the interim, Janet Petro continues to serve as acting administrator of NASA. This development occurs amid proposed significant budget cuts to NASA, with the administration’s 2026 budget proposal suggesting a 24 percent reduction, primarily affecting science programs. The space community has expressed concerns about the potential impact of these cuts on NASA’s missions and research initiatives.
