On Saturday, the former head of data for the Department of Homeland Security (DHS) expressed enthusiasm about parting ways with the current administration.
Mark Rosenblum, who previously served as the executive director of the Homeland Security Statistics Service, shared his retirement news on LinkedIn after being with the department since 2016.
He stated, “It’s been an honor to serve the nation by enhancing data quality at DHS and backing evidence-based policymaking.” However, he also mentioned feeling sad about pausing his public service career and leaving behind a strong team.
Despite this, he appeared quite relieved to distance himself from the current administration. “With ongoing issues like immigration battles, conflicts with the federal government, and challenges surrounding facts—plus the chaos and corruption happening in Iran—I think I need a change,” Rosenblum noted.
The bureau’s official website describes its mission as publishing “timely and authoritative immigration and homeland security statistics” covering various topics, including immigration, emergency management, and cybersecurity.
When the Daily Caller reached out for comment regarding Rosenblum’s departure, DHS did not clarify whether he was terminated or if he resigned voluntarily. A DHS spokesperson responded, “Opinions are always welcome, but that doesn’t mean they are factual. I don’t comment on personal decisions.”
The former secretary mentioned she would keep focusing on immigration data and policy but did not elaborate on any specific plans. Rosenblum indicated that his next endeavors would align with his own beliefs and values, which he feels resonate with many Americans.
Mike Howell, president of the Surveillance Project, remarked that Rosenblum’s resignation seemed “strange” considering the Oversight Project had just filed a lawsuit against DHS seeking the release of “actual deportation data.” He expressed a desire for transparency regarding these numbers from the government.
As of now, the White House has not addressed the Daily Caller’s inquiries or offered any clarification on whether Rosenblum was let go or chose to resign.
