Following multiple fatal shootings involving US Immigration and Customs Enforcement officers, the agency will require its officers to record vehicle stops ‌with at least one body camera, border tsar Tom Homan says.

"They exonerate more law enforcement than they convict, and I want officers to wear body cameras because I want the American people to see what the officers saw when they took that action," Homan said on Fox News.

Homan's comments come after federal immigration agents fatally shot ‌two men six ‌days apart during ⁠traffic stops in Texas and Maine earlier this month.

There is no body-camera ​footage from ICE agents involved in those incidents.

In a separate interview on CBS, Homan said money for the cameras was held up during the partial government shutdown earlier this year.

"The cameras have been purchased right now," Homan said.

"They're training the trainer in deploying the cameras nationwide."

The agency's tactics came under renewed public scrutiny in recent days after ⁠an ICE officer on July 13 killed a driver from Colombia ‌in ​the coastal Maine town of Biddeford, about 24km south of Portland.

Six days earlier, another ICE officer ​in Houston fatally ‌shot a Mexican citizen.

Homan said last week the agency would temporarily suspend most vehicle stops around the country ​to review procedures.
