Donald Trump has renominated billionaire investor Jared Isaacman to run Nasa, five months after withdrawing his first nomination.
The 42-year-old entrepreneur, who has ties to SpaceX founder Elon Musk, had looked set to lead the space agency when Trump abruptly pulled his nomination in late May, following what the president said was a "thorough review of prior associations."
While the White House did not specify what those associations were, it was during Trump's high-profile feud with Musk.
Isaacman, who is worth an estimated $1.9bn (£1.46bn), is an amateur jet pilot and also became the first non-professional astronaut to walk in space last year, on a mission with SpaceX that he bankrolled.
Why Trump has suddenly changed his mind is unclear, and the president made no mention of the past when he wrote on his Truth Social platform that he was "pleased to nominate" Isaacman for the role.
