Conservative provocateur Laura Loomer and Sen. Tim Sheehy (R-Mont.) pushed back on a decision by the White House to pull the nomination of tech entrepreneur Jared Isaacman as NASA administrator.

“A well-placed source tells me Jared Isaacman’s nomination to be the next Administrator of @NASA was set for a final Senate confirmation vote early next week, but DC insiders are now trying to convince the @WhiteHouse to pull the plug on Isaacman before his confirmation vote,” Loomer said in a lengthy post on the social platform X on Saturday.

“The final decision to pull Isaacman’s nomination could come as soon as Monday. There is reason to believe that Isaacman may be facing retaliation because of his friendship with @elonmusk,” she added. 

A White House spokesperson recently told The Hill that it was “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.”

“Astronaut and successful businessman @RookIsaacman was a strong choice by President Trump to lead NASA. I was proud to introduce Jared at his hearing and strongly oppose efforts to derail his nomination,” Sheehy said in his own X post on Saturday.

In December, President Trump unveiled Isaacman as his choice to head up NASA, calling him “ideally suited to lead NASA into a bold new Era.”

“Let me remind you who Jared Isaacman is. Yes, he has been a liberal in the past like @elonmusk, but as it relates to MERIT and his knowledge of Space, his credentials are unmatched,” Loomer said in her Saturday X post.

The Hill has reached out to the White House for comment.
