Plaintiffs in a lawsuit filed Friday claim the Education Department’s Office for Civil Rights cannot fulfill its mandated duties after nearly half the department’s staff was laid off this week, as President Donald Trump moves to shut down the agency entirely.

The layoffs call into question how agency will be able to handle major operations such as student loans, FAFSA, the Nation’s Report Card and civil rights complaints.

Under Trump’s directive the Department of Education laid off half its staff. The lawsuit argues Trump has no authority to make such drastic changes.
