HUD warned colleges that offering “affinity” student housing—or accommodations described using terms such as “diversity,” “multiculturalism,” or “safe spaces”—could violate the federal ban on racially segregated housing. The warning was tied to a federal action described in a week-in-review roundup. The reporting indicates HUD has not yet published the nonbinding Dear Colleague letter on its website, but Assistant Secretary Craig Trainor shared the letter on social media. The statement adds to broader federal scrutiny of how campus housing policies are communicated and implemented. In the same roundup, additional federal actions touched on higher-ed compliance and admissions policy, including DOJ litigation over a Kansas in-state tuition policy for certain undocumented students and an EEOC investigation into antisemitism allegations involving the National Education Association. Separately, a federal judge temporarily blocked the U.S. Department of Education from enacting new definitions around “professional” graduate degrees, citing likely failures in aligning to Congressionally set standards and alleged Administrative Procedures Act problems.
