Approximately 2,000 employees at the U.S. Agency for International Development will be let go on Sunday, with most of the remaining full-time staff placed on administrative leave overnight, according to an internal email sent to employees, CNN reports.

"All USAID direct hire personnel, with the exception of designated personnel responsible for mission-critical functions, core leadership and/or specially designated programs, will be placed on administrative leave globally," stated the email, which was sent at 2:42 p.m. ET and obtained by CNN.

"Concurrently, USAID is beginning to implement a Reduction-in-Force that will affect approximately 2,000 USAID personnel with duty stations in the United States," the message continued. Those impacted "will receive specific notifications.”

The decision is the latest in a series of drastic reductions at the federal agency, which plays a critical role in delivering humanitarian aid worldwide.

CNN previously reported that after a federal judge lifted a temporary restraining order on Friday, which had been blocking the government from placing thousands of agency employees on leave, the Trump administration proceeded with its widespread dismissals over the weekend. AFSA was among the plaintiffs in the legal case.

Among those affected earlier in the weekend were staff from USAID’s Bureau for Humanitarian Assistance, including personnel responsible for rapid disaster response efforts worldwide.
