Katie Miller, the wife of President Donald Trump’s newly appointed chief of staff Stephen Miller, has suggested that she quietly campaigned for her husband to secure the powerful White House role.
Susie Wiles was replaced by her former deputy in a shake-up that unsettled the administration following a historic midterm defeat. In response to a report claiming Katie had spent weeks urging allies to recommend her husband to Trump, she appeared to acknowledge her role.
“Wife supports husband,” she wrote on X. “If your wife doesn’t do this, find a new one.”
The confident post came after Politico reported that she had devised a strategy to propel Stephen Miller into an even more influential position after Wiles—widely viewed as one of Trump’s most trusted political operators—was set to leave the chief of staff’s office.
Trump had reportedly been considering possible replacements several weeks before the midterm “bluenami” gave Democrats control of Congress, dealing a major blow to the final two years of his second term.
Those reportedly under consideration included Federal Housing Finance Agency director Bill Pulte, special envoy Steve Witkoff, former House Speaker Kevin McCarthy and New York Yankees president Randy Levine.
The president was also said to have weighed Environmental Protection Agency administrator Lee Zeldin and U.S. ambassador to India Sergio Gor.
But Katie Miller, the 35-year-old conservative power broker, reportedly set out to ensure her husband remained in the conversation.

The Daily Mail first reported in June that Wiles could depart the White House after the midterm elections.
Wiles strongly rejected that account, describing it as “fiction” and accusing the newspaper of “trying to manufacture drama.” At the time, she insisted that she was “not going anywhere.”
Despite further assurances from Trump that no Cabinet reshuffle was planned, Katie Miller reportedly began lobbying insiders, telling them she would appreciate it if they mentioned her husband as a possible successor to Wiles.
According to Politico, she did not advocate for Wiles to be dismissed. However, one insider said Trump had made clear that he was “done with Susie” as part of his inner circle.
Once Wiles’ departure became likely, Katie reportedly made around half a dozen calls, including to Treasury Secretary Scott Bessent and trusted figures in Vice President JD Vance’s orbit, to keep Stephen Miller at the forefront of Trump’s thinking.
Trump announced the appointment early Friday on his social media platform, Truth Social.
“I am pleased to announce that Mr. Stephen Miller, the current Deputy Chief of Staff of the Trump Administration, and one of my most trusted advisors, will become the Chief of Staff starting Monday, November 9, 2026,” he wrote.

The White House presented the move as a natural progression, while Stephen Miller said he was “honored beyond words” to take on the new role. His wife’s influence in the administration is now expected to grow considerably.
With both holding substantial sway among Trump’s senior advisers, Katie and Stephen Miller have emerged as one of the most influential power couples in Republican Washington during the final two years of the president’s term.

Katie Miller expanded her profile last year by launching a podcast aimed at conservative women. Her first guest was JD Vance, followed by other senior administration officials, including Marco Rubio. Stephen Miller reportedly helped secure some of the guests.
She has also developed a reputation as an unofficial social host for the MAGA movement, holding gatherings at the couple’s home on a military base outside Washington.
The guest list has reportedly included many of the administration’s most prominent figures, among them Rubio, Treasury Secretary Scott Bessent, Defense Secretary Pete Hegseth and FBI Director Kash Patel.
She is also said to have hosted celebrations for White House press secretary Karoline Leavitt’s birthday and Todd Blanche’s confirmation as attorney general.
Born Katie Waldman, she grew up in Florida before moving to Washington, where she worked in communications for a Republican senator and later at the Department of Homeland Security during the controversy over family separations at the border in Trump’s first term.
She went on to serve as Mike Pence’s press secretary.
Katie met Stephen Miller in 2018, and the pair married two years later at the Trump International Hotel in Washington, with Trump among the guests.
Meanwhile, Wiles has faced serious corruption allegations following her removal from the White House.
A former staffer and ally of Robert F. Kennedy Jr. accused her of accepting money from corporations and foreign interests in an effort to undermine Kennedy’s Make America Healthy Again, or MAHA, agenda.
Although Trump and others have praised Wiles’ work, former Kennedy adviser Calley Means alleged during an interview with Joe Rogan that she was involved in a pay-to-play arrangement connected to her daughter.
