Can't edit, but I've seen a few more detailed timelines that roughly correspond to the parent post.
The judge didn't want ICE screwing up her courtroom (as is her right), so she declined to allow them to serve the warrant in her court.
ICE went to her boss (different part of building).
Meanwhile, she concluded her hearing with the immigrant in question and then sent him down a private stairway to exit the building.
When ICE heard what she did, they had a warrant issued for her arrest, which was then served by the FBI. So, somebody did convince a local magistrate (not a full-blown judge) to issue that warrant.
My take (IANAL)... the judge was not in the wrong for decling to serve the initial warrant. But sending the guy down a private hallway was a dumb move. Was it a federal crime? Doesn't seem like it - a slap on the wrist from her boss probably should have been sufficient.
Really, just more of the Trump administration throwing their weight around and pushing the boundaries of what's acceptable in the US.
