Since 1979, the U.S. Department of Education’s Office for Civil Rights "...vigilantly enforces federal civil rights laws in schools and other recipients of Department of Education funding throughout the nation."
Trump not only ordered thousands of disability, sexual, and racial harassment investigations to stop, including pausing the consideration of over 10,000 student complaints, but also barred the department from "...communicat[ing] with the students, families and schools involved in cases launched in previous administrations and to cancel scheduled meetings and mediations."
This includes cases such as one in Pennsylvania where white students told black students to "go pick cotton", used racial epithets, and took photos of themselves labeled "Kool Kids Klub" (KKK) among other things. Prior to the investigation, school officials said "...they saw no problem with some of the white students’ behavior and did not believe the students had created a racially hostile environment," demonstrating why these investigations are important in safeguarding students.
This order to halt investigations green-lights the poor treatment of disabled and minority students in American schools.
