And the judge said we're in, quote, shockingly unusual times.

She said she will reach a decision as soon as she can, but wants to take the time to get it right.

Minnesota says thousands of federal agents have acted so aggressively that it's infringed on the state's sovereign right to ensure public safety, and it argued the surge was politically driven.

The Trump administration insisted it's conducting legitimate immigration enforcement.

The judge noted the situation is so unprecedented, there's little case law to guide a decision.

Meanwhile, Trump is telling his border czar Tom Homan to work with Minnesota officials and report directly to him.

The state's governor, Tim Walz, says the previous official in charge, Border Patrol Chief Gregory Bovino, is leaving the state.

And he said, look, we are carrying out legitimate immigration enforcement.

Now, the judge had tough questions for both sides, including the state, and she questioned its legal theory.

One man who's been here decades and says he is in the country legally was still afraid to give his name because of how aggressive he says ICE agents are acting.

He spoke through a ski mask for warmth.

Refugees and even U.S.

citizens have been arrested.

The Trump administration has accused protesters of being violent and threatened to invoke the Insurrection Act to quell them using active military forces.
