Protesters chanted and marched Saturday outside the FBI after agents arrested a Milwaukee judge accused of helping a man evade immigration authorities. The case has escalated a clash between the Trump administration and local authorities over the Republican president’s sweeping immigration crackdown. Milwaukee County Circuit Court Judge Hannah Dugan is accused of escorting the man and his lawyer out of her courtroom through the jury door last week after learning that immigration authorities were seeking his arrest. The man was taken into custody outside the courthouse after agents chased him on foot. President Donald Trump’s administration has accused state and local officials of interfering with his immigration enforcement priorities. The arrest also comes amid a growing battle between the administration and the federal judiciary over the president’s executive actions over deportations and other matters. On Saturday, protesters chanted “Immigrants are here to stay” and held up signs saying, “Liberty and Justice for All” outside the FBI’s Milwaukee division. “The judiciary acts as a check to unchecked executive power. And functioning democracies do not lock up judges,” Democratic state Rep. Ryan Clancy told the crowd before it marched around the area. Dugan was taken into custody by the FBI on Friday morning on the courthouse grounds, according to U.S. Marshals Service spokesperson Brady McCarron. She appeared briefly in federal court in Milwaukee later Friday before being released from custody. She faces charges of “concealing an individual to prevent his discovery and arrest” and obstructing or impeding a proceeding. “Judge Dugan wholeheartedly regrets and protests her arrest. It was not made in the interest of public safety,” her attorney, Craig Mastantuono, said during the hearing. He declined to comment to an Associated Press reporter following her court appearance. Democratic Wisconsin Gov. Tony Evers, in a statement on the arrest, accused the Trump administration of repeatedly using “dangerous rhetoric to attack and attempt to undermine our judiciary at every level.” “I will continue to put my faith in our justice system as this situation plays out in the court of law,” he said. Court papers suggest Dugan was alerted to the presence of U.S. Immigration and Customs Enforcement agents in the courthouse by her clerk, who was informed by an attorney that they appeared to be in the hallway. The FBI affidavit describes Dugan as “visibly angry” over the arrival of immigration agents in the courthouse and says that she pronounced the situation “absurd” before leaving the bench and retreating to her chambers. It says she and another judge later approached members of the arrest team inside the courthouse, displaying what witnesses described as a “confrontational, angry demeanor.” After a back-and-forth with officers over the warrant for the man, Eduardo Flores-Ruiz, she demanded that the arrest team speak with the chief judge and led them away from the courtroom, the affidavit says. After directing the arrest team to the chief judge’s office, investigators say, Dugan returned to the courtroom and was heard saying words to the effect of “wait, come with me” before ushering Flores-Ruiz and his lawyer through a jury door into a non-public area of the courthouse. The action was unusual, the affidavit says, because “only deputies, juries, court staff, and in-custody defendants being escorted by deputies used the back jury door. Defense attorneys and defendants who were not in custody […]
