MILWAUKEE (AP) — The FBI on Friday arrested a Milwaukee judge accused of helping a man evade immigration authorities, escalating 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.

The judge’s arrest dramatically escalates tensions between federal authorities and state and local officials, whom President Donald Trump’s administration has accused of interfering with his immigration enforcement priorities. It also comes amid a growing battle between the Trump administration and the federal judiciary over the president’s executive actions over deportations and other matters.

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 have deep respect for the rule of law, our nation’s judiciary, the importance of judges making decisions impartially without fear or favor, and the efforts of law enforcement to hold people accountable if they commit a crime,” Evers said. “I will continue to put my faith in our justice system as this situation plays out in the court of law.”

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.
