One of the House Democrats from New Jersey under investigation by Kristi Noem’s Department of Homeland Security slammed the government’s arrest of Newark’s mayor as “un-American.” House Rep. Bonnie Watson Coleman told CNN’s State of the Union that Immigration and Customs Enforcement’s arrest of Mayor Ras Baraka is what led tensions to explode as she and two other House Democrats attempted to tour an ICE detention facility.

Rep. Rob Menendez (D-N.J.) on Sunday went after Immigration and Customs Enforcement (ICE) and Homeland Security Investigations (HSI) over recent events at an ICE detention center in Newark, N.J.
