WHITE: The Trump coalition is beginning to fracture, and in a lot of ways, there is historical precedent for this. Trump and Grover Cleveland have a lot in common besides serving non-contiguous terms as president.

Trump’s post did not clarify the status of Janet Petro, the director of the Kennedy Space Center in Florida who has been serving as NASA’s interim chief since the start of Trump’s second term.

On Wednesday evening (July 9), President Donald Trump named Sean Duffy interim chief of the space agency.

Duffy said in a post on X he was "honored to accept this mission." "Time to take over space," he said. "Let’s launch."
