WASHINGTON, D.C. (WRN) — Former Wisconsin Republican Congressman Sean Duffy has a new job.

President Donald Trump on Wednesday appointed Duffy, who is already the US Secretary of Transportation, as the acting administrator of NASA.

Trump’s previous nomination for the position was American financial businessman Jared Isaacman, an associate of billionaire Elon Musk. His name was withdrawn before the Senate could take it up for a vote.
