GEOFF BENNETT: Welcome to the "News Hour."

As we come on the air, we are tracking fallout from the latest deadly ICE shooting this time in Maine.

Yesterday, a 26-year-old Colombian national was shot and killed in Biddeford, Maine, after ICE agents attempted to pull him over while he was driving.

ICE says the man, Joan Sebastian Guerrero, seen in this independent video, tried to flee and used his vehicle as a weapon, prompting an agent to fire in what ICE says was self-defense to protect the public.

Video reviewed by the "News Hour" does not on its own confirm those claims.

As questions mount, the administration is also defending ICE's tactics more broadly.

Border czar Tom Homan said the agency has temporarily paused certain vehicle stops while it reviews recent incidents, but insisted agents acted appropriately and expects those operations to resume.

TOM HOMAN, White House Border Czar: I think what they're doing is taking a pause to make sure that, number one, the ICE officers have everything they need to stay safe, because vehicle attacks are up 3400 percent.

And they're going to make sure, is the training sufficient.

Did anything go wrong?

I'm confident they're going to get back to their policy of vehicle stops.

But they're doing what they believe is a necessary short-term pause just to look at it and make sure everything's good.

GEOFF BENNETT: Now, ICE says Guerrero was not the target of the original investigation.

His death comes after another person in Houston was killed by ICE while behind the wheel of a vehicle.

And a third man in Florida who was running away from immigration agents today was hit and killed by a tractor trailer as he tried to cross a busy street.

Senator Angus King of Maine is among a growing number of officials calling for a full investigation into the Maine shooting, and he joins us now from Capitol Hill.

Senator King, thank you for being with us.

SEN.

ANGUS KING (I-ME): Thank you, Geoff.

GEOFF BENNETT: Let's start with the facts as we know them.

I know you have been in conversation with the DHS secretary, Markwayne Mullin.

What do you understand actually transpired on the street of Biddeford, Maine, on Monday?

SEN.

ANGUS KING: Well, that's one of the problems.

We don't know.

You mentioned about video we have seen.

These guys didn't have body cameras on.

Millions and billions of dollars have been appropriated for ICE to have bodycam cameras, and they didn't have them.

And they didn't have them in Houston.

And I don't know where the body cameras are going, but they don't seem to be going to the frontline ICE agents who are endangering many of our citizens, as what happened in Biddeford.

So we start with the premise that we ought to have video, and then we'd know what happened.

Secondly, there should be a thorough, open, unvarnished investigation.

But, importantly, Geoff, it should involve state and local officials, not just ICE, DHS, and the FBI.

To be honest, those institutions just don't have much credibility right now.

And an investigation into this that doesn't have some independent verification is certainly not going to satisfy my people in Maine that the fairness and justice has been carried out.

And I got to say that whoever made this decision at DHS to suspend these vehicle stops, I think, made a good call.

And, hopefully, they will reexamine this policy, because every time something like this happens, they say, well, the vehicle was being weaponized.

But they have said that before in Minneapolis, and we also the video that indicated that wasn't the case.

So bodycams, we need.

They ought to take the masks off.

They ought to do identification.

Pretty simple, Geoff.

They ought to abide, ICE ought to abide by the same rules and guardrails of every police force in America.

And they're not doing that right now.

And what happened in Maine yesterday was an absolute tragedy, 26 years old, young man, family, 3-year-old daughter.

He wasn't the target of the investigation.

GEOFF BENNETT: Well, on the matter of the body cameras in particular, it was back in February when then-DHS Secretary Kristi Noem said that body cameras would be deployed rapidly across the country to every agent.

And, to your point, both officers in Houston and in Maine didn't have them.

How can an agency like ICE, with its funding and the tens of millions of dollars that were spent on these body cameras, how can that be the case, so far as you know?

SEN.

ANGUS KING: Beats me.

I don't understand it.

Now, I have heard from some ICE officials, well, the shutdown slowed down our contracting.

I don't buy that.

They have had their own separate funding since the reconciliation bill last year.

They have also now -- if you can believe it, they have been funded through the end of Donald Trump's term.

So they can't claim lack of funds or lack of authority to contract.

They have -- they have got the money, and this should have been taken care of a long time ago.

But the other -- here's the other point, Geoff.

The whole premise of this operation is phony.

We keep hearing and we heard all winter about the worst of the worst.

We're going to take criminals off our streets.

Well, last winter, they did a surge in Maine.

It didn't get the publicity that Minnesota did, but it was a similar kind of really disruptive presence of ICE in our -- in our largest city.

They arrested over 200 people; 19 of them had criminal records.

That means 90 percent didn't.

So this idea that they're going after the worst of the worst and getting criminals off the street is just -- is just not true.

And this is a shameful period of our history.

I talked -- I was in touch with the mayor of Biddeford this morning, the speaker of the Maine House, who also happens to be from Biddeford.

I said, has there been any crime problem in Biddeford involving immigrants?

The answer from both of them was, absolutely not.

So we don't know exactly what happened at this stop.

We want the investigation to find that out.

But the point is, they shouldn't have been there.

They shouldn't have been there in the first place.

If they want to go after with -- people with criminal records, it doesn't take these roving gangs of ICE agents that are masked and everything else.

Let them do it more carefully, rather than a sort of dragnet that in this case ended up taking down and causing the death of a young man that wasn't even part of their investigation.

GEOFF BENNETT: In the minute that remains, ICE now says they're going to temporarily stop the practice of stopping vehicles.

What needs to change before those operations resume?

SEN.

ANGUS KING: Well, I think the first thing that needs to be changed is what we were just talking about, is body cameras.

They should not be doing these stops unless they're body cameras so that we have definitive evidence of exactly what happens in the course of one of these stops.

That's number one.

Number two is more training for these agents.

Apparently, the agent who shot the young man in Biddeford had just been with the agency, I think, less than a year.

And the question is whether he had the training that it is involved in a traffic stop.

There's a lot of law about shooting at cars by police force and by law enforcement.

You don't do it unless you or some member of the public is in imminent danger.

And that's got to be part of this training.

So I would say body cameras, get rid of the masks, and more training, and then also de-escalate this whole thing.

The final point is, Geoff, these ICE agents are being given quotas from the White House of how many people to arrest a day.

It was 3,500.

Now I understand it's 2,000.

That's a awful way to make this kind of policy, because you're going to get these kind of terrible results.

They ought to quit that.

Let's go after the criminals.

Everybody agrees with that, but let's get out of this dragnet through our cities and our communities.

Maine, Biddeford, Maine, doesn't deserve this.

GEOFF BENNETT: Senator Angus King of Maine, thank you for speaking with us this evening.

SEN.

ANGUS KING: Thank you, Geoff.

GEOFF BENNETT: And a note.

The "News Hour" requested interviews with the homeland security secretary and the head of ICE.

Those requests were declined.
