More than a dozen anti-ICE agitators hauled away by NYPD near Columbia University

It is unclear if the agitators were students or staff affiliated with the university.

Officers said agitators were blocking the school's entrance and refused to leave.

Video showed the agitators wearing black T-shirts that read, "Sanctuary Campus Now" and "ICE Off Campus."

Multiple orders to disperse were given. The NYPD says the orders were disobeyed roughly 20 minutes.

The agitators were taken into custody. 

"To be clear, the University requires ICE to have a judicial warrant to access non-public areas, such as classrooms, housing, and other areas requiring a Columbia University ID," university officials wrote. "An administrative warrant is not sufficient to access non-public areas of the University. We have a clear protocol for potential visits from U.S. Immigration and Customs Enforcement (ICE) Agents, which are publicly available on our website."

"As we made clear repeatedly, no member of Columbia's leadership or the board of trustees has ever requested the presence of ICE agents on or near campus," the school added. "This is a false assertion."

Following the ruling, the American Civil Liberties Union (ACLU) claimed the opinion does not take effect immediately and the Trump administration cannot lawfully re-detain Khalil while he has the opportunity to seek immediate review.
