The U.S. Marshals Service confirmed Judge Hannah Dugan was arrested at about 8 a.m. at the Milwaukee County Courthouse.

A judge in Milwaukee is accused of helping a man evade immigration authorities. The case has immediately become a high-profile confrontation between the Trump administration and the judiciary over immigration policies.

A Wisconsin judge has threatened to refuse to hold court following the arrest of Judge Hannah Dugan last week. Dugan was arrested by federal authorities for allegedly helping a man who was in the United States illegally avoid arrest by Immigration and Customs Enforcement officers.
