Marc Rosenblum, the executive director of the Office of Homeland Security Statistics, resigned, labeling the Trump administration’s immigration enforcement as a “war on immigrants.” His departure highlights growing concerns over data transparency and politicized policy within the agency.

Key Takeaways

  • Marc Rosenblum resigns as DHS’s top statistics official
  • He publicly condemns the administration’s “war on immigrants”
  • Data transparency at DHS has sharply declined under the second Trump term

Marc Rosenblum, who served as executive director of the Office of Homeland Security Statistics (OHSS) and deputy assistant secretary, announced his resignation on LinkedIn, stating, “Between the war on immigrants, the war on feds, and the war on facts, I just need a change.”

Rosenblum, a veteran of both the first Trump and Biden administrations, originally oversaw immigration statistics before expanding his portfolio to cover the entire department’s data—from cyber‑intrusions to trafficking investigations. The office peaked at 45 staffers during the Biden years, but began shrinking after Trump’s 2024 inauguration.

He had pledged faster, more granular data releases in 2023, yet the OHSS website has not been updated since February 11, 2025, leaving analysts scrambling for reliable information through FOIA lawsuits. Critics argue the agency now offers only curated press releases, not raw data.

Historical Background

The Department of Homeland Security was created in 2002 after 9/11 to centralize national security functions. Over two decades, DHS grew to include immigration enforcement, cyber‑security, and emergency management. However, the second Trump term intensified aggressive immigration raids, ballooning detention facilities, and a pattern of data suppression that eroded public trust.

Why This Matters

BozokMedia analysis shows that the resignation underscores a growing rift between career civil servants committed to data integrity and an administration that prioritizes political narratives over factual reporting.

“When facts become inconvenient for the administration, transparency becomes a casualty,” said a senior policy analyst.
Did You Know?: DHS oversees 22 component agencies, each historically maintaining siloed data sets that complicate agency‑wide analysis.
