The FBI has arrested a Milwaukee judge accused of helping a man evade immigration authorities. Friday's arrest escalates a clash between the Trump administration and local authorities over the president’s sweeping immigration crackdown.

The Justice Department said Hannah Dugan refused to turn over a man wanted by immigration agents and that she tried to help him evade arrest by allowing him to exit through a jury door.

U.S. District Judge Paul Friedman ruled that a key part of President Donald Trump’s March 27 order can’t be enforced at roughly three dozen agencies and departments where employees are represented by the National Treasury Employees Union.

A judge on Thursday sided with San Francisco and other cities in barring the Trump administration from denying or conditioning the use of federal funds to 'sanctuary' jurisdictions.
