He quickly found a home in Jeff Sessions’ Senate office, helping to torpedo bipartisan immigration reform efforts with arguments that, even then, echoed white nationalist rhetoric. His admiration for 1920s immigration laws, designed to keep out non-European migrants, was evident in leaked emails where he praised Calvin Coolidge for “shutting down immigration” and encouraged Breitbart News to feature articles from extremist sources. When the Southern Poverty Law Center published those emails, they revealed a man fixated on race, always searching for new ways to frame immigration as an existential threat to white America.
It was this unyielding worldview that made Miller a perfect match for Donald Trump. Unlike most of the political world, Miller saw Trump’s 2015 campaign announcement—the one where he called Mexican immigrants rapists and criminals—as an opportunity rather than a catastrophe. “As soon as I saw it, I said, ‘I have to join his campaign,’” Miller recalled. Within days, he had reached out to Steve Bannon, secured a meeting, and was inside Trump’s orbit.
From that moment on, Miller became the architect of some of the most draconian immigration policies in modern American history. The Muslim travel ban? That was Miller. The policy of separating families at the border? Miller again. The relentless push to make asylum virtually impossible? Miller’s fingerprints were all over it. “No nation can have the policy that whole classes of people are immune from immigration law or enforcement,” he declared, defending the family separation policy in a 2018 interview. “The public wants to see an immigration system that protects American jobs, American wages, and America’s communities.”
The backlash was fierce, but Miller thrived on it. His smirk became a familiar sight on television screens as he dismissed criticism with a blend of contempt and calculated righteousness. When a judge ruled against one of the administration’s immigration orders, Miller scoffed, calling it “patently unlawful” and “an assault on democracy itself.” He had no patience for legal barriers; he saw them as obstacles to be ignored, overridden, or bulldozed entirely.
Even after Trump’s first term ended, Miller refused to fade into the background. He founded America First Legal, a right-wing legal group designed to fight diversity and inclusion initiatives across the country. It was, in essence, a shadow government waiting for Trump’s return. When that moment came in 2024, Miller stepped back into power without missing a beat.
Now, as Trump’s second administration barrels forward, Miller is orchestrating what one official described as “a bloody mass deportation agenda.” He has openly boasted that the operation will be “greater than any national infrastructure project” in U.S. history. The administration has already begun invoking the Alien Enemies Act to justify mass deportations, including efforts to expel Venezuelan nationals to third countries like El Salvador. When a judge tried to halt one of these deportation flights, the administration ignored the ruling, sending the plane into international airspace anyway. “That is not something that a district court judge has any authority whatsoever to interfere with,” Miller said flatly, brushing aside the legal challenge.
To Miller, the law is only useful when it serves his agenda. He has no interest in compromise, no concern for the human cost of his policies. What he does have is a vision—one that is colder, harsher, and fundamentally different from anything America has seen in modern times. He is not just reshaping immigration policy; he is attempting to reshape the very identity of the nation.
Those who have worked with Miller say he is driven by something deeper than politics.
