Who is Katie Miller? DOGE Spokeswoman leaving White House with Elon Musk

Katie Miller , a seasoned political advisor and communications strategist, has officially departed the White House alongside Elon Musk following the end of their roles as special government employees. Miller, who previously served as an advisor and spokeswoman for Musk’s Department of Government Efficiency ( DOGE ), is now set to work for him full-time. Her transition marks a significant move in Musk’s continued involvement in U.S. policy and government reform initiatives, especially after his highly publicized 130-day stint in Washington, D.C. Miller’s influence in both political and tech circles has made her a central figure in the DOGE initiative.


Katie Miller's husband, Stephen Miller , a White House official, and rumours around the couple
Katie Miller is married to Stephen Miller, the White House deputy chief of staff, according to insiders cited by WIRED. Katie, who served as the spokesperson for Elon Musk’s Department of Government Efficiency (DOGE), will now work full-time for Musk. Meanwhile, social media has been rife with rumours speculating that Katie left her husband Stephen Miller for Elon Musk, suggesting the three were involved in a “throuple” during Musk’s time at the White House. Katie acted as the crucial link between Musk and the administration, often delivering bad news to him, while she and Stephen also helped navigate Musk through Washington. Rumors suggest Stephen Miller “used” his wife as Musk’s handler and bragged about controlling Musk, though these remain unconfirmed. A senior Republican strategist described Katie as a powerful figure who “leaves bodies everywhere she’s been.” Despite Musk’s exit signalling possible tensions with Trump, some Republicans like Vice President JD Vance believe Musk’s political influence will continue, cautioning that the “Elon era” is far from over.





Katie Miller’s early life and rise in Republican communications
Katie Miller holds a BA from the University of Florida and a Master of Public Policy from George Washington University. She began her political career as a press assistant for the National Republican Senatorial Committee, later serving as press secretary for Senator Steve Daines and spokeswoman for Senator Martha McSally. In 2017, she joined the Department of Homeland Security as deputy press secretary, where she defended the Trump administration’s family separation policy. She went on to serve as press secretary and then communications director for Vice President Mike Pence, becoming a key figure in Republican communications.


DOGE and the Elon Musk partnership
In December 2024, Donald Trump announced Miller’s appointment to the newly formed Department of Government Efficiency (DOGE), where she became a close advisor to Elon Musk. According to WIRED, she was a key intermediary between DOGE and the rest of the White House, responsible for delivering daily messaging and managing Musk’s political communication.
Miller’s responsibilities grew to include coordinating Musk’s media appearances, particularly around SpaceX’s Starship launch and broader tech policy. Her influence in DOGE was described as "pivotal" by insiders, and she helped shape Musk’s messaging and manage sensitive government interactions.
Departure from the White House
Musk’s tenure as a special government employee ended in May 2025 after 130 days, and Miller’s term concluded alongside his. Following their departure, CBS News confirmed that Miller would continue working for Musk full-time, leading communications across his ventures. Her shift to the private sector marks a new phase in their professional collaboration.


Road ahead for Katie Miller

Katie Miller's unique role bridging government policy and technological innovation positions her as an influential figure in both political and tech worlds. As Musk plans to step back from political spending and re-evaluate his role in public policy, Miller’s communications acumen will likely continue to play a major role in shaping the public narrative around Musk’s ventures.
Her next chapter, outside of government but still within the realm of high-stakes influence, will be closely watched as Musk’s enterprises continue to blur the line between Silicon Valley and Washington, D.C.
