This comes as tensions are rising at Columbia University in New York, where police have arrested more than 100 people in recent days during ongoing protests over the Israel/Hamas War.

The Anti-Defamation League says it's seen an uptick in antisemitic attacks. Incidents have about doubled, according to the ADL's annual audit of antisemitic incidents.

Pennsylvania has seen these acts quadruple.
In New Jersey, incidents have nearly doubled, with the Garden State now ranking at the top in terms of incidents per capita.
Higher institutes of learning, including the University of Pennsylvania and Drexel, have also seen an alarming rise, showing antisemitic incidents have more than doubled since 2022.

The Jewish Federation of Greater Philadelphia says it had to increase security after a rash of incidents, including a bomb threat against chapters in Philadelphia, Harrisburg, Pittsburgh and Lehigh Valley earlier this month.

"We've increased the number of people at institutions -- armed guards, security cameras. We've increased the number of deputies we work with," said Michael Balaban, with the Jewish Federation of Greater Philadelphia.
The FBI will be monitoring large gatherings, as well as high-profile events and symbolic places, for acts of violence during Passover, which is observed through April 30.
