The Ivy League university, an epicenter for protests last year, says it is “expediting” its investigation into a group who disrupted a class on Israeli history Tuesday.

Columbia University says it is boosting security after an incident on campus involving protesters. Earlier this week, the university said in a statement a class on "The History of Modern Israel" was disrupted Tuesday by a group of students who handed out fliers showing violent imagery.

These people are openly against not just discussion, they’re openly against anyone in the university learning about the history of Israel,” one student told The Post.
