Billionaire Jared Isaacman, who has been to space twice and is Trump's pick to head NASA, could be one step closer to confirmation after a hearing.

Isaacman was nominated by Trump in December, and sat before the committee for a hearing on April 9. With the vote to secure his position as NASA Administrator on an imminent path, Isaacman stands to replace former administrator Bill Nelson, and take the reins from the current acting administrator, Janet Petro.
