WASHINGTON (AP) — Dozens of Democratic U.S. senators and the Independent senator from Maine pushed for more details Monday from Immigration and Customs Enforcement about the agency’s vetting practices for new agents and how officers conduct vehicle pursuits, even as they demanded that body cameras be swiftly rolled out to all officers.

The demands came in a letter spearheaded by Maine’s Independent Sen. Angus King, signed by 38 Democratic senators and sent to the Department of Homeland Security, which oversees ICE. The demands follow two deadly shootings in which ICE officers shot and killed immigrants in Houston and Maine.

The Associated Press reported last week that the ICE officer in Maine who opened fire and killed a man from Colombia had a history of violent behavior toward family members that was detailed in family court records.

His first ex-wife, Ashley Brouillette, told AP he was physically violent with her, including once throwing boiling water at her while she was holding their child.

His second ex-wife, Lucinda Brouillette, sent a statement over the weekend alleging “a persistent pattern of abuse, intimidation, manipulation, fear, and control.”

“Throughout our marriage and in the years that followed, I have feared for a long time that his anger, aggression, and escalating behavior would eventually result in severe, life threatening violence, and I often believed I would be the one on the receiving end of it,” she wrote.

Hundreds of pages of family court documents describe their turbulent marriage, and the years after. Lucinda Brouillette told the court he had stalked and harassed her and physically and verbally abused his daughter, according to multiple requests for temporary protection orders. Brouillette tackled his teenage daughter and smashed spaghetti in her hair, and during another outburst, he dragged his daughter around the house as she cried, she said.

“Dave needs counseling or something for his PTSD & depression,” she wrote in an application for a temporary protective order on behalf of his teenage daughter which a judge granted in 2021.

In court filings, David Brouillette said that his second ex-wife had slandered him.

Multiple family members told the AP the government should have never given him a gun, badge and the authority to patrol city streets as the Trump administration ramps up its mass deportation agenda.

The senators’ letter on Monday listed new measures to increase accountability at the agency, including transparency about whether ICE considers records from family court of domestic violence or abuse when vetting new recruits.

“We remain supportive of removing dangerous convicted criminals from our communities, but this goal can and must be achieved without endangering these very communities in the process. By no stretch could either of the victims in Texas and Maine be characterized as ‘the worst of the worst,’ making these tragic deaths even more egregious,” the senators wrote. “The American people deserve clarity and accountability.”

They said ICE should immediately start wearing uniforms or vests that clearly identify them as “ICE” instead of the more generic “POLICE” or “POLICE ICE.” Civil rights groups and advocates have often criticized ICE for not wearing uniforms or clear identification on their ballistics vests identifying them as deportation officers.

Senators also demanded to know what changes were being made to how officers conduct traffic stops and vehicle pursuits.

The shootings in Maine and Houston both involved ICE officers shooting at people who were in vehicles at the time. In the wake of the Maine shooting, Homeland Security temporarily stopped officers from conducting vehicle stops except in specific situations. But just a day later, after fierce criticism from some MAGA supporters, President Donald Trump said on social media that traffic stops should continue.

Homeland Security said last week that it was adding new training in crowd-control measures, high-risk vehicle stops, live-fire exercises and medical training, in response to what they called coordinated attacks against their officers and ICE facilities.
