In April, a county judge in Wisconsin was arrested on allegations that she'd deliberately misdirected federal immigration agents to try and assist a criminal illegal alien whom those agents were after in evading capture.

On Friday, newly released surveillance video footage appeared to confirm the allegations that Milwaukee County Circuit Judge Hannah Dugan did indeed send federal agents on a wild goose chase to try and help Mexican national Eduardo Flores-Ruiz avoid arrest, Fox News reported.

Dugan has pleaded not guilty to the pair of federal charges against her, for which she could be imprisoned for up to six years if convicted, and instead has argued that she is protected from criminal prosecution by judicial immunity.

Video footage released

On April 18, Flores-Ruiz -- a Mexican national previously deported in 2013 who'd returned unlawfully and had an administrative warrant against him -- arrived at the courthouse in Milwaukee and met with his attorney for a hearing with Judge Dugan about a trio of domestic battery charges filed against him, according to the released video footage.

Waiting to arrest him in a public hallway outside the courtroom were several federal agents with Immigration and Customs Enforcement, Customs and Border Patrol, the Drug Enforcement Administration, and the FBI.

Judge Dugan became aware of the presence of the federal agents and confronted them in the hallway, during which she falsely asserted that they needed a special judicial warrant to make an arrest inside the courthouse, and sent them to the chief judge's office to obtain the legally unnecessary document.

While the agents were away, Dugan then cancelled the domestic battery hearing for Flores-Ruiz -- even though his alleged victims were present in the courtroom -- and instead guided Flores-Ruiz and his attorney to a side hallway exit typically reserved for jurors.

Meanwhile, one of the agents had returned to the main hallway, observed and followed the wanted illegal alien and his attorney as they exited the building, and then was joined by other agents in a brief foot pursuit outside the courthouse that ultimately ended with Flores-Ruiz being apprehended about a block away.

Judge pleads not guilty, moves for dismissal of charges

According to a Justice Department press release, Judge Dugan, 65, has been charged with "obstruction of proceedings before a department or agency of the United States, which carries a maximum penalty of five years in prison, and concealing a person to prevent arrest, which carries a maximum penalty of one year in prison."

The written account of her alleged criminal acts, now confirmed by the released surveillance camera footage, made it clear that the judge knowingly and willfully interfered with the lawful efforts of federal agents to catch a wanted criminal illegal alien, whom she attempted to unlawfully conceal from said agents.

Fox News reported that Dugan, who was arrested about one week after the courthouse incident, recently pleaded not guilty to the criminal charges that were handed down against her by a federal grand jury.

Dugan and her attorney have taken that defense a step further, however, and filed a motion to summarily dismiss the charges because she is "entitled to judicial immunity for her official acts."

"Immunity is not a defense to the prosecution to be determined later by a jury or court; it is an absolute bar to the prosecution at the outset," her motion insists.
