Milwaukee County Circuit Judge Hannah Dugan pleaded not guilty Thursday in federal court to charges alleging she interfered with federal immigration enforcement by assisting a noncitizen avoiding arrest by US Immigration and Customs Enforcement (ICE).

Judge Dugan is facing two federal charges, the first being concealing an individual to prevent arrest, and the second obstruction of justice. The charges stem from an April 18 incident in which she allegedly helped a man identified as Eduardo Flores-Ruiz, who is reportedly in the US without legal status, exit her courtroom through a back door to evade ICE agents waiting in the courthouse.

The arraignment took place in the US District Court for the Eastern District of Wisconsin, where Magistrate Judge Stephen Dries scheduled a trial to begin on July 21. Dugan’s attorney, Steven Biskupic, stated the trial is expected to last approximately one week.

Federal prosecutors allege that Dugan’s actions constituted active interference with federal law enforcement. FBI Director Kash Patel claimed in a public statement that the judge’s conduct “misdirected” immigration agents and “created increased danger to the public.” ICE agents reportedly arrested Flores-Ruiz at a later time.

In a motion filed Wednesday, Dugan’s attorneys moved to dismiss the charges, arguing that she was acting in her official judicial capacity and is therefore immune from federal prosecution. They further assert that the federal government’s decision to prosecute a sitting state judge constitutes a violation of Wisconsin’s state sovereignty and amounts to inappropriate federal interference in state judicial proceedings. If convicted on both counts, Dugan could face up to six years in federal prison.

Neither Dugan, her legal team, nor federal prosecutors spoke to the media following Thursday’s hearing.
