The Wisconsin judge who allegedly helped an illegal migrant evade immigration authorities pleaded not guilty through her attorney on Thursday.

Judge Hannah Dugan from Milwaukee County made a preliminary plea in federal court. The courtroom was filled with protesters showing their support for the judge. She has emerged as a symbol of defiance against the immigration policy of the Trump administration.

Dugan was arrested last month after being accused of obstruction of justice and concealing Mexican national Eduardo Flores-Ruiz from federal law enforcement.

She is accused of rushing Flores-Ruiz, who is accused of domestic battery, out of her courtroom and encouraging him to use an exit that is not usually available to the public to help him evade immigration agents who were there to bust him.

She has denied wrongdoing in the case.
