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 lawsuit claims that decimating the agency’s Office for Civil Rights will leave it unable to address issues of discrimination at school — violating the equal protection clause of the Fifth Amendment.

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.
