President-elect Donald Trump announced today that he has selected Peter Navarro to serve as his trade and manufacturing adviser.

Navarro was the director of the National Trade Council during Trump’s first term. “In my first term, few have been more effective or unyielding than Peter in implementing my two sacred rules: buy American (products), hire Americans,” the president-elect said in his Truth Social post.

Navarro was sentenced last January to four months in jail for contempt of Congress for ignoring a subpoena he received from the committee investigating the January 6, 2021, attack by Trump supporters on Capitol Hill.

Trump also picked Jared Isaacman, a close associate for years of Ilon Musk and his space company SpaceX, as the new head of NASA. Isaacman is CEO of payment management company Shift4 Payments and head of Polaris, a program to send private astronauts into orbit around Earth on SpaceX spacecraft.

“Jared (…) will pave the way for groundbreaking achievements in science, technology, and space exploration,” Trump said.

If his nomination is approved, Isaacman will head a $25 billion agency whose goal is to resume manned missions to the moon, with the Artemis program, which Trump promoted during his first term. That program will rely heavily on SpaceX’s Starship spacecraft.
