The Trump administration is planning to shutter the Office of Environmental Justice and External Civil Rights at the Environmental Protection Agency and has placed nearly 170 employees on administrative leave.

Environmental Protection Agency employees who work in the environmental justice and civil rights office expect a new round of paid leave notices that will impact even more federal workers, four sources familiar with the matter told CNN.

In an email obtained by NPR, employees at EPA's Office of Environmental Justice and External Civil Rights were told they were on administrative leave, effective immediately.
