An “emergency rally” in Manhattan on Saturday aims to criticize the Trump administration after ICE agents arrested Newark, NJ Mayor Ras Baraka and accosted several Members of Congress outside a federal detention center Friday.

Baraka, a Democratic candidate for New Jersey governor, was taken into custody Friday after attempting an unannounced inspection of Delaney Hall, a privately run ICE facility in Newark. The arrest came during a protest where Baraka was joined by elected officials, including two New Jersey members of Congress.
