The wife of an ex-college professor convicted of terrorism-related charges was spotted hanging out at Columbia University’s encampment prior to the dramatic raid — as Mayor Eric Adams on Wednesday blamed outside agitators for the campus chaos.

Adams said the NYPD had already started to identify individuals who weren’t Columbia students before cops were given the green light late Tuesday to oust a pro-terror mob who took over an academic building on campus.

While he didn’t name anyone specifically, Hizzoner told MSNBC that “one of the individual’s husband was arrested for and convicted for terrorism on a federal level.”

Sami al-Arian — who pleaded guilty in 2005 to fund-raising and other support for the the terrorist group Palestinian Islamic Jihad –had boasted on social media that his wife, Nahla, was among those who joined anti-Israel protesters at the Ivy League campus last week.
