A federal judge on Friday blocked the Trump administration from terminating the collective bargaining rights for a sizeable share of the federal workforce.

Senior U.S. District Judge halted the executive order amid a union lawsuit representing 160,000 federal workers.

Specifically, the complaint says Dugan assisted Eduardo Flores-Ruiz, a Mexican immigrant, avoid being arrested by federal immigration officials at the Milwaukee County Courthouse after he appeared in her courtroom for a pre-trial conference on April 18.

Hannah Dugan, the Milwaukee judge accused of helping a man evade immigration authorities, is known for running a strict courtroom while also being a familiar face in the community, particularly at interfaith events.

A Milwaukee County Circuit judge was arrested by the FBI Friday and charged in federal court for allegedly helping an undocumented immigrant avoid arrest.

Judge Hannah Dugan was arrested on suspicion that she “intentionally misdirected federal agents away from” an immigrant being pursued by the authorities, the F.B.I. director said.

The arrest appears to heighten the stakes in the Trump administration's aggressive actions against judges who have challenged its immigration crackdown.
