The American Association of University Professors sued the Texas Tech University System in federal court, challenging Chancellor Brandon Creighton’s systemwide memoranda that the faculty groups say impose an “extraordinary system of censorship.” The complaint argues professors can no longer teach or assign certain materials and “factual information about race,” discuss aspects of Holocaust persecution of gay and bisexual men, or use works such as Plato’s Republic, due to classroom-instruction limits tied to race, sex, gender identity, and sexual orientation. AAUP and the Texas A&M University System are seeking a court order to block enforcement, while a system spokesperson says Texas Tech is “confident” its policies are lawful, constitutionally sound, and compliant with state and federal law. According to the lawsuit, an approval process for course content delayed instruction, produced inconsistent determinations, and fueled self-censorship among faculty, with internal emails and faculty testimony cited in the 84-page filing.
