Minnesota Congresswoman Ilhan Omar today introduced a bill that aims to ban schools from shaming students who are unable to pay for their school meals.

Omar was joined today by Valerie Castile–the mother of the late Philando Castile. Philando was a cafeteria worker who routinely paid for students’ lunches from his own pocket if they did not have enough money. He was killed by a police officer during a traffic stop in 2016. Earlier this year, Valerie gave Robbinsdale Cooper High School in New Hope, Minnesota $8,000 to settle students’ lunch debts in honor of her son.
