Two days after Republicans suffered a sweeping defeat in Tuesday's midterm elections, President Donald Trump signalled he had no interest in conciliation. On Friday he elevated Stephen Miller — his longtime, bare-knuckled policy adviser — to replace Susie Wiles as White House chief of staff, installing a partisan firebrand in one of the most powerful jobs in Washington just as Democrats prepare to take control of both chambers of Congress.
"The mission now is more clear than ever: fight with all of our soul to support our president and defend this magnificent republic," Miller wrote on X, calling himself "honored beyond words" to take the post. Trump told reporters: "Stephen Miller's been with me since the beginning. He gets it."

The chief of staff controls access to the Oval Office, sets the White House agenda and leads negotiations with Congress — exactly the role Miller, best known as the architect of the administration's aggressive deportation operations, will now occupy opposite a newly empowered Democratic majority. He has also reportedly driven US military operations against suspected traffickers in Venezuela and the Caribbean that critics have condemned as extra-judicial killings, and he drew scrutiny this year for calling Alex Pretti — killed by federal immigration officers during a Minneapolis deportation operation — a "domestic terrorist" and "assassin," before walking the comments back.
Wiles, who co-managed Trump's 2024 campaign, had cultivated a reputation for calm management that avoided the staffing chaos of his first term. Speculation that she might be replaced had circulated for days before Friday's announcement, amid reports that Trump's patience had frayed as his approval sank — a decline that culminated in Tuesday's rout.
Reaction split sharply along party lines. House Democratic leader Hakeem Jeffries called Miller "a dangerous xenophobe and reckless extremist who has American blood on his hands," saying his "presence in government should be eradicated like a malignant tumor." Utah Senator Mike Lee countered that Miller had been "a true conservative warrior" and "a steadfast fighter for President Trump for over a decade." Retiring North Carolina Senator Thom Tillis, by contrast, has called him "incompetent" and "the architect of some of the dumbest proposals from the Trump White House."
The appointment complicates Vice-President JD Vance's suggestion, made days after the midterms, that Republicans should refocus enforcement on employers rather than individual migrants — polling found 58% of voters now believe the administration's immigration crackdown has "gone too far," and Hispanic voters broke decisively against Republican candidates. Miller will also have to negotiate with an incoming Senate that includes Texas Democrat James Talarico, whom Miller mocked on social media earlier this year as "their first transgender Senate candidate." With congressional Democrats promising fresh investigations into the administration, Trump appears to be betting that a fighter, not a conciliator, is what his final two years in office require.
