The Trump administration fired about 1,300 additional employees at the Interior Department over the holiday weekend, according to two people familiar with the matter, adding to the widespread purge of thousands of federal workers with probationary status that began last week.
The Trump administration had also fired about 1,000 employees at the National Park Service, according to workers groups, bringing the total number of layoffs at the Interior Department to roughly 2,300.
The firings affected many agencies that oversee public lands controlled by the federal government and are managed by the Interior Department.
Some of those agencies focus on areas that President Trump has made policy priorities. Mr. Trump said last week that he had directed Doug Burgum, the interior secretary, to undo a Biden-era ban on offshore drilling, and he has in recent weeks fixated on water supply issues that plagued the response to recent wildfires in California.
Among those fired over the weekend were workers at the Bureau of Reclamation, which manages water resources in parched western states, and the Bureau of Ocean Energy Management, which has long overseen offshore drilling, and, more recently, offshore wind farms.
The cuts also included people from the Fish and Wildlife Service, and the Bureau of Land Management, which oversees the conservation and use of public land.
