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 the judiciary over the Republican president’s sweeping immigration crackdown.

FBI Director Kash Patel announced on social media the arrest of Judge Hannah Dugan, who he said “intentionally misdirected” federal agents away from a man they were trying to take into custody at her courthouse.

“Thankfully our agents chased down the perp on foot and he’s been in custody since, but the Judge’s obstruction created increased danger to the public,” Patel wrote.

Dugan appeared briefly in federal court in Milwaukee on Friday before being released from custody. Her next court appearance is May 15.

“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.

The arrest comes amid a growing feud between the Trump administration and the judiciary over the White House’s immigration enforcement policies. The Justice Department had previously signaled that it was going to crack down on local officials who thwart federal immigration efforts.

Court documents detailing the case against the judge were not immediately available, and the Justice Department didn’t immediately have a comment Friday.

A person answering the phone Friday at Dugan’s office said he could not comment. The Associated Press left an email and voicemail Friday morning seeking comment from Milwaukee County Courts Chief Judge Carl Ashley.

The Justice Department in January ordered prosecutors to investigate for potential criminal charges against state and local officials who obstruct or impede federal functions. As potential avenues for prosecution, a memo cited a conspiracy offense as well as a law prohibiting the harboring of people in the country illegally.

Dugan was elected in 2016 to the county court Branch 31. She also has served in the court’s probate and civil divisions, according to her judicial candidate biography.

Before being elected to public office, Dugan practiced at Legal Action of Wisconsin and the Legal Aid Society. She graduated from the University of Wisconsin-Madison in 1981 with a bachelor of arts degree and earned her Juris Doctorate in 1987 from the school.
