The White House announced Monday that President Donald Trump is withdrawing the nomination of Scott Socha to lead the National Park Service, without providing an immediate explanation for the move.

Socha, a hospitality executive serving as president of parks and resorts at Delaware North, had been nominated earlier this year to oversee the federal agency responsible for managing hundreds of national parks and historic sites across the United States.

The National Park Service is currently being led by acting director Jessica Bowron, who also serves as the agency’s comptroller. The agency has not had a Senate-confirmed director during Trump’s current term, mirroring the leadership structure of his first administration.

Socha’s withdrawal comes amid broader changes within the park service, including workforce reductions tied to the administration’s efforts to shrink the size of the federal government. Thousands of employees have reportedly left or been dismissed since Trump returned to office.

The administration has also proposed significant budget reductions for the agency, including plans to cut staffing levels and reduce overall funding in upcoming fiscal years. Congress partially blocked previous proposals to scale back funding following opposition from lawmakers and advocacy groups.

Some conservation organizations had questioned whether Socha’s background in the private sector would translate to managing the park system, which includes a wide range of natural and historical sites across the country.

The Interior Department has not announced a replacement nominee, and it remains unclear when a new candidate to lead the National Park Service will be put forward.
