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.
