>> First off tonight, the face of President Donald Trump's aggressive mass deportation push spent this morning on the hot seat over federal agents use of tear gas on protesters.

Us District Court Judge Sarah Ellis grilled Border Patrol Chief Greg Bovino over whether he had violated restrictions.

She put in place more than 2 weeks ago.

She also gave, you know, some orders going forward or Heather.

Sharon joins us now with details about today's high stakes hearing.

Heather.

So federal agents they've deployed tear gas against residents of 3 Chicago neighborhoods.

3 days in a row.

Did judge ellos think that the agents were justified?

Know she said that there was nothing she saw on the videos that has blanketed our airwaves and airwaves across the nation.

>> That made it clear that federal agents were justified in using that level of force.

She said she didn't see any threat from protesters loudly.

Yes, but permissible E objecting to their presence in their neighborhoods.

Now, Judge Ellis said she could think of only 3 reasons for that They had not understood her order to they hadn't read her order and she said the 3rd recent was unthinkable.

Certainly federal agents who take an oath to support and defend the Constitution would not violate a lawful order issued by a federal judge.

So she spent most of the hour and 15 minutes.

Bovino was on the stand question him closely about the order making it short, making sure he understood exactly what she had ordered into what action did the judge take?

Did she find that?

But, you know, did violate order.

She did not.

But she made it clear that she was deeply, deeply concerned.

And Greg Bovino now has to do 2 things in the coming days.

He has obtain and be trained on how to use of body-worn camera.

He told her today he has not had won, even though he's been, as we said, the face of this mass deportation push for months.

And she says that she wants to see him in her chambers every weekday at 06:00PM so that she can give her an in-person recap of what's happened on the streets of Chicago.

A startling intervention by a federal judge in this ongoing immigration enforcement.

So as she spent a significant amount of time, also questioning the vino about the deployment of tear gas and older park on Saturday morning while she's so concerned about that.

>> Well, that morning started for many residents in that neighborhood on the northwest side of Chicago as one that was going to be fun.

It was the neighborhood's annual Halloween parade and they were focused on that.

But mid morning agents arrived and attempted to detain a construction worker.

They believed to be in the country without permission.

>> When residents came out of their house and objected to that, they tackled at least 2 Rest Inc, taking them to the street and then as they left deployed, tear gas just spewing it throughout the neighborhood.

Now Ellis was furious.

She said there was no like there's no way that children preparing for Halloween parade, present a clear and present danger to agents.

And she said that she was angry that apparently these children sense of safety in their home neighborhoods may have been shattered, perhaps forever.

So this order, it also requires federal agents to wear identification.

But many of them captured on video conducting these raids.

They don't appear to have done so.

Ellis asked of, you know about that.

She did and she got a to agree that he would again issue this order to the agents that he commands, saying that they have to cook conspicuously displayed a badge number, a last name, some sort of information that it well would allow.

Alice and other people keeping tabs on these raids like journalists to figure out who is doing what Ellis said that she did not want to see future videos where she was struggling to identify the agents involved.

What happens next?

Well, Bovino will be in court for his first daily appearance at 06:00PM Tomorrow she was hopeful that agents had gotten the message in today's hearings and they would not deploy tear gas against the people.

Chicago again.

And she says if they do, they better be prepared to quote, back it up.

And if they don't, she would be prepared to ban the use of tear gas by federal agents as the plaintiffs in this case had asked her to do today pay more to come, of course, had room.

Thanks so
