In His Words: Stephen Miller's Hardline Immigration Views and Bombastic Attacks on Democrats

Stephen Miller has a new title: White House chief of staff. The man who has shaped many of President Donald Trump's signature domestic policies, above all the sweeping immigration crackdown, now runs the president's operation at a hard moment. Republicans have lost both houses of Congress, and the White House faces a difficult lame duck stretch. Democrats are expected to examine Miller's record closely, and that record is largely in his own words.

Miller has defended Trump's most far-reaching efforts to remake government since the 2016 campaign, and he is known for harsh language that draws outsized attention from supporters and critics alike. On immigration, he told Fox News Channel in December 2023, during a spike in illegal border crossings, "We are being conquered." He spoke of millions arriving with different cultures and belief systems, and warned that a generation from now people would not recognize their country. Only deportations by the millions, he said, could prevent consequences he called permanent. Many of those crossing were fleeing poverty and violence.

The human cost is plain in the case of Alex Pretti, a 37-year-old Minneapolis resident shot and killed by federal agents in January during protests against the administration's immigration policies. Miller posted on social media that Pretti was a "domestic terrorist" and an "assassin" who had "tried to murder federal agents." He later said in a statement that the officers in Minneapolis "may not have been following" protocol.

That same month, after a U.S. military operation captured Venezuelan President Nicolás Maduro, Miller wrote on X against what he called "reverse colonization," arguing that Western nations had long punished themselves for the sake of the developing world. He defended a U.S. claim to Venezuela's oil, writing that American toil created the industry there and that its expropriation was the largest recorded theft of American wealth. Speaking to CNN's Jake Tapper, he said the world is governed by strength, force and power. In that interview he also said Greenland should obviously be part of the United States, and that nobody would fight the U.S. militarily over it. Denmark, which controls Greenland, is a NATO ally.

In May 2025, Miller said the administration was actively looking at suspending habeas corpus, the right to challenge detention in court, to speed deportations. He cited the Constitution's allowance for suspension in a time of invasion, and said much depended on whether courts "do the right thing." In the nearly 18 months since, Trump and his administration have not publicly pursued the idea.

His earlier record runs through the first term. He championed family separation at the border, telling The New York Times in 2018 it was a zero tolerance policy and that "no one is exempt from immigration law." The policy provoked widespread outcry and was not revived in the second term, though mass deportations have still divided families by legal status. In 2017, at the White House briefing room, he laid out plans to cut green cards and favor English speakers and skilled workers. Asked about the Statue of Liberty poem, he said it was added later and was not part of the original statue.

When the Supreme Court blocked Trump's attempt to end birthright citizenship, Miller told Fox in June that the ruling was a "deep knife wound in the heart of the American republic," and that a reading of the Constitution requiring a nation to "suicide" its civilization was wrong.

He has also voiced skepticism about childhood vaccines. In August he praised Trump's executive order aimed at curtailing the children's vaccine schedule. Miller, a father of four including an infant born in June, said parents feel pressured to give babies five, six or seven shots at once and that "nobody has studied it." The CDC says research shows receiving several vaccines at once does not cause chronic health problems.

Of Democrats, he said in August 2025, while defending National Guard deployments in Washington and other cities, that the party does not fight for American citizens, and that it is "not a political party" but "a domestic extremist organization." With Miller now running the West Wing, those words will be tested against the oversight a Democratic-led Congress can bring.
