Jared Isaacman and President Donald Trump have met in recent weeks and discussed reviving the fintech billionaire’s nomination to lead NASA, according to a person familiar with the matter.

A decision to reconsider the Elon Musk ally would mark a major reversal for Trump after the White House revoked the job offer in May citing Isaacman’s ties to Democratic politicians. That left NASA without a long-term leader as the space agency grapples with funding and job cuts and races to bring astronauts back to the moon.
