DHS Official Resigns, Citing ‘War on Immigrants’

The Department of Homeland Security’s apical numbers-cruncher has resigned, citing the Trump administration’s “war connected immigrants” connected his mode out.

DHS has been a hub of contention during the 2nd Trump term: the ICE raids successful American cities, the chaotic spending, the increasing archipelago of detention centers, the attempts to fell information astir it all. But vanishingly fewer officials person near the section and been openly captious of the absorption it has taken. Marc Rosenblum, who served arsenic enforcement manager of the Office of Homeland Security Statistics and a lawman adjunct caput astatine the department, is 1 of the first.

“I’m thrilled to extremity my narration with the existent administration,” Rosenblum said successful a LinkedIn station implicit the weekend. “Between the warfare connected immigrants, the warfare connected feds, and the warfare connected facts (not to notation the brainsick warfare successful Iran and the brazen corruption), I conscionable request a change.”

Rosenblum besides served successful the archetypal Trump and Biden administrations, initially moving DHS’s bureau of migration statistics, and past overseeing stats for the full department—collating numbers connected everything from cybersecurity intrusions to trafficking investigations to deportations. His bureau peaked astatine 45 radical successful the Biden years, and started to shrink since.

“He had 1 of the astir absorbing charges astatine DHS,” a erstwhile workfellow tells WIRED of Rosenblum. “There's 22 constituent agencies, and truthful determination are 22 antithetic ways of aggregating information that were conscionable wholly siloed.”

“So Marc's complaint was to consolidate each the information and enactment it successful a mode that internally, I astatine office could cognize precisely however galore Coast Guard interdictions happened disconnected the Coast Guard presumption successful Miami, and however galore of those were Cuban, Haitian, Nicaragua, Venezuelan. And past benignant of conceptualize that with the aforesaid colonisation of radical that were crossing the Southwest border,” the erstwhile workfellow adds.

A home information bureau similar DHS is ne'er going to beryllium a exemplary of transparency. But Rosenblum, a long-time migration argumentation wonk and an migration specializer for the Congressional Research Service, promised arsenic overmuch openness arsenic imaginable erstwhile helium took connected his department-wide relation successful 2023. “We’ll statesman releasing information much quickly, with greater granularity and covering a broader scope of DHS activities,” helium told Federal News Network that November.

That information itself became arguable successful Trump 2.0. The Office of Homeland Security Statistics’ website connected ICE detentions, Border Patrol encounters, and DHS repatriations hasn’t been updated since February 11, 2025, conscionable weeks into the 2nd Trump term. What accusation has been pried from DHS since then, often done Freedom of Information Act lawsuits, has been astatine times spotty and unreliable, analysts say.

“There’s nary accountability, nary mode to assess, nary nationalist knowing astir what’s truly going connected that is not curated by a property merchandise from the agency,” David Bier, the Cato Institute’s manager of migration studies, told NOTUS successful November.

DHS didn’t instantly respond to a petition to remark for this story. Neither did Rosenblum. But helium did allude to the trouble of publishing prime information nether this medication successful his LinkedIn post. “My OHSS co-workers are outstanding vocation national civilian servants. They are smart, mission-focused experts who nutrient precocious prime results successful a challenging and often hostile enactment environment,” helium wrote.

“Marc was precisely what each American should privation successful a vocation nationalist servant,” Luis Miranda, a apical DHS spokesperson during the Biden years, tells WIRED. “The Trump medication has governed by silencing oregon ignoring facts and accusation they judge doesn’t enactment up with their utmost rhetoric, and that has damaging implications, truthful it's nary astonishment vocation officials whose occupation is transparency are incapable to bash those jobs.”
