The Wisconsin judge who was arrested by the FBI on Friday and accused of interfering in the arrest of an undocumented immigrant has a decadeslong history of advocating for the poor and vulnerable.

Brady McCarron, spokesman for U.S. Marshals Service in Washington, D.C., confirmed Dugan was arrested at about 8 a.m. at the Milwaukee County Courthouse and is in federal custody.

Hannah Dugan, the Milwaukee judge accused of helping a man evade immigration authorities, is known for running a strict courtroom while also being a familiar face in the community, particularly at interfaith events.
