California Gov. Gavin Newsom has signed a law aimed at combating antisemitism at schools. It creates an an Office of Civil Rights to work with districts on fighting discrimination and bias and requires an antisemitism prevention coordinator within the office to submit recommendations to the Legislature. Proponents say the law is needed to respond to an alarming level of harassment against Jewish students. But critics say it could unintentionally stifle instruction and open dialogue in the classroom. Lawmakers in several other states have tried to advance similar proposals.
