The Trump administration recently pulled Jared Isaacman's nomination to be NASA administrator, alluding that he was not in "complete alignment" with the president's agenda.
"The Administrator of NASA will help lead humanity into space and execute President [Donald] Trump's bold mission of planting the American flag on the planet Mars," White House Assistant Press Secretary Liz Huston told Fox News Digital on Saturday.
Huston added it is "essential" that the next leader of NASA "is in complete alignment" with President Trump's "America First" agenda.
A replacement will be announced directly by Trump "soon," according to the White House.

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.

Sen. Tim Sheehy, R-Mont., who introduced Isaacman to the Senate Committee on Commerce, Science and Transportation, described him as "a successful innovator, entrepreneur, pilot, and astronaut."
"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."

"For nearly 70 years, the United States has been at the forefront of space exploration," he continued. "President Trump knows how critical it is to reinvigorate NASA so we can once again lead the world to new heights, and that's why he chose exactly the right man for the job: Jared Isaacman."
