"Under President Trump, the EPA will be focused on our core mission to protect human health and the environment," Administrator Lee Zeldin wrote in a statement.

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.
