A conservative advocacy group filed a legal challenge against Chicago Public Schools on Friday over an initiative to give extra support to Black students, calling the program discriminatory under federal civil-rights laws and in violation of recent guidance from the Trump administration.

Last year, a Virginia-based advocacy group challenged a Los Angeles Unified School District initiative aimed at boosting outcomes for its Black students, which CPS said inspired its own plan. At the urging of the Biden administration, Los Angeles made changes to downplay the role of race, causing an outcry from some of its initiative’s supporters.
