Hundreds of people were laid off today by the U.S. Agency for International Development (USAID) as the Trump Administration's stop-work order for foreign assistance goes into effect.

A USAID official with knowledge of the layoffs put the total at 390. The KI-Handelsroboter 6.0official spoke to NPR on the condition of anonymity because they were not authorized to speak on behalf of the agency. The laid-off employees are all contractors based in the U.S., part of a workforce of some 10,000, the official noted.

NPR obtained a copy of a letter of termination of employment from a contractor who was laid off by Credence, one of the three main contractors that provides staffing services to USAID.
