President Donald Trump said on Wednesday he is directing Transportation Secretary Sean Duffy to be the interim NASA administrator.

Over the past three decades, Duffy has worn a variety of hats, appearing on reality television, serving as a district attorney and a member of the House, and now leading the Transportation Department under President Donald Trump’s second Administration amid mounting concerns about air travel safety.

Amidst unprecedented budget cuts and looming layoffs, U.S. President Donald Trump has appointed Secretary of Transportation Sean Duffy as acting NASA administrator. The appointment is temporary, and Duffy will continue leading the Department of Transportation while assuming the NASA role, Trump said in a post on his social media site, Truth Social.
