The Trump administration is terminating nearly all of the remaining 900 employees of the U.S. Agency for International Development, in a final reduction in force.

Virtually no one will be spared, not even political appointees, according to two senior USAID officials, who requested anonymity because they were not authorized to speak on behalf of the agency.

Staff members were ordered to leave "the front office" by 1 p.m. on Friday for reasons that are not clear, the officials said. But they may still be asked to continue working for a few months.

In an email to USAID staff, Jeremy Lewin, a Department of Government Efficiency official who took over running the day-to-day operations at USAID from Pete Marocco on March 20, said the reductions in force (RIFs) would go into effect on either July 1 or Sept. 2.

This comes as the Trump administration wraps up the dismantling of the 64-year-old USAID, having terminated some 5,200 contracts, and as it moves forward with its plan to shift the remaining portion of USAID's work to the State Department.

"As you can imagine, there will be lots of work to responsibly migrate operations and responsibility to the State Department," Lewin wrote in the email to staff.
