University of Pennsylvania law professor Amy Wax sued the school for racial discrimination on Thursday, escalating a long-running clash with administrators over her controversial statements on race.

Wax was suspended from Penn Law for a year following high-profile comments questioning the academic ability of Black students and hosting a white nationalist speaker in her class.

Law-school professor at the University of Pennsylvania sues her Ivy League employer over her suspension in September, arguing the school’s speech policy is racially discriminatory and violated her First Amendment rights.

A White Jewish professor has sued the University of Pennsylvania for breach of contract, accusing the institution of “racist double standards” for suspending her over race-related comments while allowing other employees to smear Jews without consequence.

Amy Wax has filed a lawsuit alleging Penn's speech policies violate the First Amendment and are "racially discriminatory."
