President Donald Trump announced on Tuesday that he will once again nominate Jared Isaacman, the tech billionaire and astronaut, to serve as Administrator of NASA, reversing his earlier decision to withdraw Isaacman’s nomination amid concerns about his political background.
Trump had initially nominated Isaacman in the spring but withdrew the nomination in late May, citing a “thorough review” of Isaacman’s “prior associations.” At the time, Trump expressed surprise over Isaacman’s political history, describing him as a “blue-blooded Democrat who had never contributed to a Republican before,” despite acknowledging that he thought Isaacman “was very good.”
Isaacman, the founder and CEO of Shift4, a payment-processing company, is also known for his collaborations with SpaceX and its founder Elon Musk. He has financed several private spaceflights, including the first private spacewalk, and has played a key role in promoting commercial space exploration.
Trump’s renewed nomination comes as his relationship with Musk appears to have improved following a public falling out earlier this year. The two were seen together at conservative activist Charlie Kirk’s funeral in Arizona last month, and Trump recently told reporters that he and Musk have been speaking “on and off” and that their relationship is “good.”
In his Truth Social post announcing the renomination, Trump made no mention of his earlier reversal. Instead, he praised Isaacman’s credentials, writing:
“This evening, I am pleased to nominate Jared Isaacman, an accomplished business leader, philanthropist, pilot, and astronaut, as Administrator of NASA. Jared’s passion for space, astronaut experience, and dedication to pushing the boundaries of exploration make him ideally suited to lead NASA into a bold new era.”
Transportation Secretary Sean Duffy has been serving as interim NASA administrator since Isaacman’s initial withdrawal. Trump commended Duffy for doing an “incredible job” in the interim.
Isaacman’s nomination had previously cleared the Senate Commerce, Science and Transportation Committee in April, and a full Senate vote was expected before Trump unexpectedly pulled it. With his renomination, the process will now restart.
In his own social media post Tuesday, Isaacman thanked Trump for renewing his confidence in him and expressed gratitude to the “space-loving community,” though he did not address the earlier controversy surrounding his withdrawn nomination.
SpaceX, which maintains extensive contracts with NASA, is expected to play a significant role in the agency’s future missions — a partnership likely to continue under Isaacman’s leadership if confirmed.
