Saying the Trump administration is sabotaging civil rights enforcement by the Department of Education, a federal lawsuit filed Friday morning seeks to stop the president and Secretary Linda McMahon from carrying out the mass firing of civil rights investigators and lawyers.

Two parents and the Council of Parent Attorneys and Advocates, a national disability rights group, jointly filed the lawsuit. It alleges that decimating the department’s Office for Civil Rights will leave the agency unable to handle the public’s complaints of discrimination at school. That, they said, would violate the equal protection clause of the Fifth Amendment to the U.S. Constitution.
