Black students at Cornell University say they “do not feel safe” on campus as a graduate student from the United Kingdom, Momodou Taal, is facing deportation after his participation in a “menacing” anti-Israel protest earned him a suspension.

Mamadou Taal, a Ph.D. student in Africana Studies, was suspended Monday by the university after he took part in a protest against a career fair attended by defense contractors L3Harris and Boeing last week. Taal is studying at Cornell on an F-1 student visa, which can be terminated by a suspension.

International doctoral student Momodou Taal could lose his F-1 visa after he was suspended over his role in a campus protest against companies that provide weapons to Israel.
