Mullin: 1.1K CISA staff left DHS amid partial shutdown

The Hill reports that Homeland Security Secretary Markwayne Mullin disclosed that the Cybersecurity and Infrastructure Security Agency (CISA) lost approximately 1,100 employees during a 76-day partial government shutdown in 2025, which occurred amid a Democratic push for federal immigration reform following two killings by immigration enforcement personnel in Minnesota. The article is sourced from a named, experienced reporter at a major national outlet, though the provided excerpt does not include direct quotes from Mullin or other officials, which limits transparency about how the figure was obtained or contextualized. Independent coverage from Politico, Federal News Network, and HSToday corroborates the shutdown duration and indicates broader organizational damage across DHS, with Politico noting that recovery could take months—adding important context about downstream impacts beyond raw headcount loss. Critical readers should monitor DHS operational capacity assessments and whether the 1,100 departures include both furloughed workers who returned versus permanent attrition, as this distinction significantly affects long-term agency function.
