Trump to withdraw Jared Isaacman's nomination as NASA chief
"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," she added.
The move comes as something of a surprise. Trump announced his choice of Jared Isaacman in December, before the president's inauguration, and the nominee seemed poised to be confirmed by Congress as soon as next week.
Huston's statement doesn't give an overt reason for dropping the 42-year-old Isaacman, the founder and CEO of the payment-processing company Shift4. But it seems to imply that the White House doesn't think Isaacman is fully on board with Trump and his space priorities.
