Watch: NASA nominee Jared Isaacman faces Senate confirmation hearing

Tech entrepreneur Jared Isaacman, President Trump’s pick to lead NASA, testified before the Senate Commerce, Science and Transportation Committee on Wednesday.

Isaacman, who previously worked with SpaceX CEO Elon Musk to test the company’s new spacesuits on the first private spacewalk. He helped fund the flight and was one of four people aboard.

The confirmation hearing came less than a month since the return of NASA astronauts Suni Williams and Butch Wilmore, who spent more than nine months on the International Space Station after the Boeing Starliner mission was upended by aircraft issues. The president suggested last month that he would pay overtime costs to them for their trouble.

Senators also questioned Olivia Trusty on her nomination to become a member of the Federal Communications Commission.

The event was scheduled to begin at 10 a.m. EDT.
