NEW YORK — Insisting demonstrations at Columbia University have “been co-opted by professional outside agitators,” New York City Mayor Eric Adams on Tuesday told students to leave their makeshift encampment.

The Democratic mayor, flanked by NYPD brass at police headquarters, addressed the public during a foreboding press briefing that hinted at future chaos and possible arrests. He insisted people who “have no affiliation with Columbia University” and have sinister motives have overtaken the mostly peaceful protests in support of Palestinians on the Upper Manhattan campus.

“It is our belief they are now actively co-opting what should be a peaceful gathering,” Adams said. “This is to serve their own agenda. They are not here to promote peace or unity or allow a peaceful displaying of one voice but they are here to create discord and divisiveness.”
