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.
Public DHS data dashboards tracking key metrics such as ICE detentions and Border Patrol encounters have reportedly not been updated since February 2025, raising questions about transparency during a period of intensified enforcement.
Rosenblum is among several high-ranking DHS officials who have departed since Trump’s second inauguration, including the acting ICE director and multiple acting FEMA chiefs.
Unlike many others, however, Rosenblum chose to go public with sharp criticism of the president’s agenda.
His resignation follows the earlier dismissal of Homeland Security Secretary Kristi Noem and the exits of her top deputies.
Conservative observers view Rosenblum’s departure as a welcome development for an administration determined to reverse the Biden-era policies that allowed millions of illegal crossings.
By framing routine deportations and border security measures as a “war,” Rosenblum revealed the ideological resistance that career bureaucrats often pose to elected leaders seeking to fulfill their mandate from American voters.
Rosenblum’s decision to air grievances on LinkedIn while exiting underscores a broader tension inside the federal bureaucracy.
Officials who spent years under administrations that prioritized leniency now face an environment focused on results: removing criminal aliens, deterring illegal entries, and restoring order.
His claim of a “war on facts” rings hollow to those who watched official statistics balloon under previous leadership without corresponding accountability.
As the Trump administration continues its work to enforce the law, the departure of officials uncomfortable with that mission may clear the way for greater alignment between policy and execution.
