Trump admin pulls Jared Isaacman's nomination for NASA administrator, replacement to be announced 'soon'

Huston added it is "essential" that the next leader of NASA "is in complete alignment" with President Trump's "America First" agenda.

Trump later took to Truth Social to confirm the ousting.

"After a thorough review of prior associations, I am hereby withdrawing the nomination of Jared Isaacman to head NASA," the president wrote in a post. "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!"

Isaacman is the billionaire founder and CEO of Shift4 payments, a credit card payment processing company.

He reportedly dropped out of high school as a teen, using a $10,000 check from his grandfather to form his tech business.

"Jared believes in NASA's core mission," Sheehy told Fox. "He has the experience and skillset to ensure we continue to lead in the greatest frontier ever known, and I look forward to adding NASA administrator to his already remarkable resume."

The White House did not immediately respond to Fox News Digital's request for comment.
