An anonymous student filed the complaint on Monday.
They accuse the university of failing to protect Jewish students from antisemitic harassment in the months following the October 7th attack on Israel.
The complaint goes on to say the student's educational experience at Northwestern was quote "unbearable" due to a "hostile environment."
