White House pulls Jared Isaacman’s NASA nomination: What’s next?

In what is a shocking development, the White House will pull Jared Isaacman’s NASA Administrator nomination for unknown reasons ahead of its full Senate vote next week. This opens the door for another individual to step into the role that has been left vacant for over 100 days in one of the most troubling times in the agency’s existence.

In what would have been an easy vote, Jared Isaacman’s confirmation will no longer take place next week. The Senate was planning to take up the vote once it returned from its Memorial Day recess on Monday. Experts state that at least 70 Senators would have voted yes for Isaacman’s confirmation.

However, the White House confirmed reporting by Semafor’s Burgess Everett that it no longer wished to see Isaacman confirmed as NASA Administrator.

“The Administrator of NASA will help lead humanity into space and execute President Trump’s bold mission of planting the American flag on the planet Mars. It’s essential that the next leader of NASA is in complete alignment with President Trump’s America First agenda, and a replacement will be announced directly by President Trump soon,” Liz Huston, a spokesperson for the White House, told Semafor.

No reason was given; however, reading between the lines of the White House statements, it is clear President Trump was not pleased with something Isaacman said, believed, or didn’t say about the future of NASA.

President Trump’s only public statements about NASA’s future have been about gearing the agency up for landing Americans on Mars, with returning to the Moon necessary but not exciting enough to be mentioned in one of President Trump’s speeches.

During Isaacman’s confirmation hearing, the subject of Mars vs. Moon has been a hotly debated one, with Senators from both sides, including the leading Senator on space, Texas Senator Ted Cruz, being clear that NASA’s goal must be to return to the Moon before China.

Isaacman also spoke in favor of NASA’s science missions, a division set for near dismantling by President Trump’s 2026 budget. To make things worse for Isaacman in the eyes of the President, he has been a supporter of DEI programs at his companies over the years.

With Musk now out of the White House and making public statements against Trump’s “One Big Beautiful Bill,” saying, “I think a bill can be big, or it could be beautiful,” in an interview with CBS, Isaacman could have been collateral damage.

What does this mean for NASA?

For NASA, this means we are back to square one in finding a confirmed NASA Administrator to fill the position. For now, Acting Administrator Janet Petro will continue in her role but has limited ability to perform the full duties of a confirmed appointee.

As Ars Technica’s Eric Berger puts it best, this is “a likely disaster for NASA.”

Isaacman, despite the concerns surrounding his close ties with Musk, loved space and loved NASA. If in charge, he would likely have done good work for the agency, advocating for its continued growth.

However, the change in appointments now likely means the next nomination will be a closer ally of President Trump than anything else. Berger states there were two potential administrator choices six months ago, a budget cutter and Isaacman. Who that other potential nominee is remains unknown.
