Amidst a sea of youg college students at the protest, breaking into a building and denying Jewish students access to the campus, was an eldery woman taunting the protesters and inciting them.

Police identified the woman as Lisa Fithian. She credits herself with ‘shutting down the CIA’, occupying  Wall Street, and other major protests in recent American history.

Among the throng of Columbia University student protesters gathered outside Hamilton Hall on campus early Tuesday morning was a gray-haired woman in her 60s.

In a video captured by The New York Times, the protesters can be seen trying to push their way toward the building as the woman — decades older than the crowd — pleads with two young counterprotesters trying to block them from barricading the occupied building.
