DHS Data Chief Quits, Blasts Trump Admin’s Border Enforcement

Another day, and another leftist government official is resigning.

A longtime Department of Homeland Security official who oversaw the agency’s critical statistics office has resigned, launching a scathing public attack on President Donald Trump’s immigration policies and branding the administration’s enforcement efforts a “war on immigrants.”

Marc Rosenblum, the executive director of the Office of Homeland Security Statistics and a deputy assistant secretary, announced his departure in a LinkedIn post over the weekend after more than a decade at the department.

“I’m sad to suspend my career in public service and leave my amazing team,” Rosenblum wrote.

“But it will come as no surprise that I’m thrilled to end my relationship with the current administration. Between the war on immigrants, the war on feds, and the war on facts (not to mention the crazy war in Iran and the brazen corruption), I just need a change,” he whined.

Rosenblum, who also served in the first Trump administration and under President Joe Biden, added that he looks forward to a new role focused on immigration data and policy “with goals that actually align with my values and those of most other Americans.”

He praised his colleagues as “smart, mission-focused experts who produce high-quality results in a challenging and often hostile work environment.”

The Office of Homeland Security Statistics is responsible for compiling and publishing official data across DHS operations, including border encounters, deportations, ICE detentions, cybersecurity threats, and trafficking investigations.

Rosenblum joined DHS in 2016 at the Office of Immigration Statistics and later expanded his role to lead the broader statistics office created during the Biden years.

A DHS spokesperson pushed back firmly against Rosenblum’s characterization of the administration’s work.

“People are always welcome to their opinion — that doesn’t make it right or factual,” the spokesperson told reporters.

Rosenblum’s exit comes amid President Trump’s aggressive push to restore border security and conduct mass deportations of illegal immigrants after record encounters under the previous administration.

Critics of Rosenblum’s remarks note that describing lawful enforcement of immigration statutes as a “war on immigrants” reflects the open-borders mindset that contributed to chaos at the southern border for years.
