A federal judge ordered the Trump administration to reinstate roughly 25,000 federal employees.The temporary order is the latest example of the fight over President Donald Trump's mass firings.DOJ filings in the case also provide extensive details about the terminations thus far.New documents filed by the Justice Department shed light on just how far the White House and its DOGE office have gone in trying to cut probationary staff from the federal government.In declarations from 18 departments or agencies, officials said roughly 25,000 federal workers had been terminated across the government. Their disclosures are the largest insight yet into mass reductions that have become the signature focus of President Donald Trump's first 100 days in office.Agency officials were required to file the declarations by Monday night in a legal case brought by 20 Democratic state attorneys general which allege that the mass firings were illegal. US District Court Judge James K. Bredar previously granted the attorneys general request to temporarily restrain the Trump administration from fully carrying out the terminations.Many of the roughly 25,000 employees were put on administrative leave following their reinstatement, according to the filings. Some agencies have struggled to notify fired workers that they can come back. An IRS official said they had resorted to sending out certified mail.Agency officials repeatedly warned that complying with Bredar's order could cause chaos, especially if the temporary block is lifted and the workers are fired again. Even if employees can return to work, many officials said in the filings any reinstated employee would have to go through the onboarding process again, requiring them to obtain security badges, complete training, and receive whatever equipment they needed for their jobs. Some of the agencies said they don't have enough office space.The White House targeted probationary employees with less than two years of experience in their roles as early as Inauguration Day. Probationary employees are typically easier to terminate since they lack some civil service protections.The DOGE office was not directly responsible for the Office of Personnel Management memo that prompted agencies to review the status of their probationary employees. Tesla CEO Elon Musk, the de facto leader of the DOGE office, has championed mass firings and claimed credit for at least some efforts to reduce the size of government, namely the US Agency for International Development (USAID).Here are the agencies that have been hit the hardest so far, according to the filings.Treasury DepartmentThe Treasury Department terminated 7,605 out of roughly 16,663 probationary employees.The IRS is by far the largest affected Treasury agency with 7,315 terminated employees.The Department of Treasury, the second-oldest Cabinet department, manages federal finances, ensures financial security, and, through the IRS, collects taxes.Agriculture DepartmentThe Agriculture Department terminated roughly 5,714 employees.The department said that on March 12, it reinstated all of the affected employees and put them on administrative leave as part of a phased plan for them to return to work.USDA is responsible for food, nutrition, and rural development.Health and Human Services DepartmentThe Department of Health and Human Services terminated 3,248 out of roughly 8,466 probationary and trial period employees.
