DHS Official Resigns, Citing ‘War on Immigrants’

Department of The director of Homeland Security resigned, citing “Trump’s war on immigration” on his way out.

DHS has been a source of controversy during Trump’s second term: the ICE is raiding American citiesuseless money, and the size of the islands of the confined spacetrying to hide most of it all. But it seems that only a few officials have left the department and have been openly criticizing the way it has been run. Marc Rosenblumwho served as the director of the Office of Homeland Security Statistics and assistant secretary of the department, is one of the first.

“I am happy to end my relationship with the current administration,” said Rosenblum in a LinkedIn post at the end of the week. “Between the war on immigration, the war on food, and the war on truth (not to mention the crazy war on Iran and acne), I just need to change.”

Rosenblum also served in Trump and Biden’s first administrations, first running the DHS office of immigration statistics, then managing statistics for the entire department-aggregating numbers on everything from cybersecurity intrusions to commercial investigations to evictions. His office swelled to 45 people during the Biden years, and has been shrinking ever since.

“He had one of the most interesting cases at DHS,” a former colleague told WIRED of Rosenblum. “There are 22 entities, so there are 22 ways to integrate data that is completely encrypted.”

“So Marc’s case was to put it all together and put it in such a way that internally, I at headquarters would know exactly how many of the embargoes were done at the Coast Guard station in Miami, how many were Cuban, Haitian, Nicaraguan, Venezuelan.

A homeland security agency like DHS is not an obvious example. But Rosenblum, a long-term immigration policy and an immigration expert for the Congressional Research Service, promised to be more open when he took his job across the department in 2023. “We will start releasing data faster, with more granularity and covering more DHS operations,” he he told the Federal News Network that November.

The same became controversial in Trump 2.0. Office of Homeland Security Statistics’ website on ICE detentions, Border Patrol encounters, and DHS deportations have not been updated since February 11, 2025, just weeks before Trump’s second executive order. What information has been released from DHS since then, often Freedom of Information Act casesthere have been times mine are unreliable, experts say.

“There is no accountability, there is no monitoring system, there is no public understanding of what is going on that is not controlled by the media from this organization,” said David Bier, director of incoming studies at the Cato Institute. he told NOTUS in November.

When asked about Rosenblum’s resignation and his “war on immigration” comment on LinkedIn, a DHS spokesperson said in a statement, “People are always welcome to their opinions — that doesn’t make them right or true.

Rosenblum did not respond to a request for comment, but mentioned the difficulties of publishing good data under this administration in his LinkedIn. “OHSS employees are elite federal government employees. They are highly skilled, focused professionals who deliver high-quality results in a demanding and often brutal job,” he wrote.

“Marc is exactly what every American should want in the public service,” Luis Miranda, DHS’s chief spokesman during the Biden years, told WIRED. “The Trump administration monitors and suppresses or ignores facts and information it believes are inconsistent with its extremist agenda, and has damaging consequences, so it’s no surprise that public officials whose jobs are in the public eye can’t do those jobs.”
