Columbia University said Friday that it has banned a student protest leader from campus after a video resurfaced Thursday that showed the student saying Zionists "don't deserve to live."

A university spokesperson said the student, Khymani James, has been "banned from campus." The university did not provide any further details on the circumstances surrounding the ban or offer any information on disciplinary proceedings.

In a statement Friday night about the ongoing protests, Columbia officials said a person whose "vile videos" had recently surfaced has been banned.

"Chants, signs, taunts, and social media posts from our own students that mock and threaten to 'kill' Jewish people are totally unacceptable, and Columbia students who are involved in such incidents will be held accountable," the statement said.
