Hannah Dugan, a Milwaukee County Circuit Court judge, was arrested by the FBI on Friday for allegedly trying to help an undocumented defendant avoid arrest.The big picture: The Wisconsin judge's arrest comes as the Trump administration ramps up its battle against the judicial branch and tests its executive power to enforce the president's immigration policies.

The FBI's arrest of Wisconsin Judge Hannah Dugan is meant to scare officials and others from "standing up to the Trump regime," says Democrat State Rep. Ryan Clancy.
