A senior Homeland Security official is leaving the Trump administration, and he’s making it crystal clear he won’t miss it.
Marc Rosenblum, the executive director of the Office of Homeland Security Statistics, announced his resignation with a parting message that amounted to a public rebuke of the administration’s immigration agenda.
“It will come as no surprise,” Rosenblum wrote on LinkedIn, “that I’m thrilled to end my relationship with the current administration.”
He didn’t stop there.
Rosenblum said he’s equally excited that his next job will allow him to continue working on immigration policy “with goals that actually align with my values and those of most other Americans”—a not-so-subtle swipe at Trump’s hardline immigration crackdown.
While he didn’t reveal where he’s headed next, the message left little doubt about how he views the administration he’s leaving behind.
The Department of Homeland Security brushed off the criticism.
“People are always welcome to their opinion—that doesn’t make it right or factual,” a DHS spokesperson told reporters. “We will not comment on personal decisions.”
Rosenblum isn’t a political newcomer or a partisan activist.
He’s spent more than a decade at DHS, serving under both Democratic and Republican administrations, including President Barack Obama, President Joe Biden, and Trump’s first administration. Before joining DHS, he served on Obama’s Immigration Policy Transition Team and held a leadership role at the Migration Policy Institute.
His work has earned bipartisan respect. Just recently, Rosenblum received an award from the nonpartisan Data Foundation honoring federal employees who use data to improve public policy.
Former DHS spokesperson Luis Miranda said Rosenblum represented exactly what Americans should want in a career civil servant.
“Marc was exactly what every American should want in a career public servant,” Miranda told Wired.
Miranda also accused the Trump administration of sidelining facts whenever they conflicted with its political narrative.
“The Trump administration has governed by silencing or ignoring facts and information they believe doesn’t line up with their extreme rhetoric,” he said. “It’s no surprise career officials whose job is transparency are unable to do those jobs.”
Rosenblum’s views on immigration have been on the record for years.
In testimony submitted to the Senate in 2015, he warned that large-scale deportation policies come with serious human and economic costs.
“The deportation dilemma is that more humane enforcement is fundamentally in tension with stricter immigration control,” Rosenblum wrote at the time. “A robust enforcement system inevitably inflicts damage on established families and communities.”
Those concerns have become increasingly relevant as the Trump administration ramps up mass deportation efforts and expands immigration enforcement across the country.
Now, one of the department’s own top experts is walking away, and doing so with a blunt message that the administration’s approach to immigration no longer aligns with either his values or, he argues, those of most Americans.
