Katie Miller, wife of the newly appointed White House Chief of Staff Stephen Miller, has alluded to her involvement in his promotion, stating, "If your wife doesn't do this, find a new one." Her comment on social media followed reports that she actively lobbied within the Trump administration to position her husband for the role.
Politico reported that Katie Miller strategized a plan to elevate her husband's standing after Susie Wiles, previously considered a close Trump confidante, was reportedly no longer serving as the president's chief of staff. Trump had been considering several candidates for the position, including Bill Pulte, Steve Witkoff, Kevin McCarthy, Randy Levine, Lee Zeldin, and Sergio Gor.
However, Katie Miller reportedly took steps to ensure her husband was considered, making calls to individuals such as Treasury Secretary Scott Bessent and associates of JD Vance to advocate for Stephen Miller. Trump announced Stephen Miller's appointment as Chief of Staff on November 9, 2026, citing him as a trusted advisor.
The Millers have become an influential couple within the Trump administration. Katie Miller, previously known as Katie Waldman, has hosted events and her podcast has featured prominent conservative figures. She previously served as a communications professional for a Republican senator and the Department of Homeland Security, and later as Mike Pence's press secretary.
Meanwhile, Susie Wiles has reportedly faced accusations of corruption, with a former aide to Robert F. Kennedy Jr. alleging that Wiles accepted money from corporations and foreign entities to undermine Kennedy's agenda. Wiles had previously denied reports of her departure from the White House in June, calling them "fiction."
