Communications work (2014–2021) By March 2014, Waldman had begun working for the
National Republican Senatorial Committee as a press assistant. She later served as a deputy press secretary for the department. As the
Trump administration's
family separation policy mounted in 2018, Waldman falsely claimed that immigration officials were not separating children from families. Waldman and
Stephen Miller, a
senior advisor to the president and the
director of speechwriting, sought to reinstate the policy, according to
Vanity Fair. In September, Waldman became vice president
Mike Pence's press secretary. In February 2020, Waldman married Miller at
Trump International Hotel Washington, D.C. Miller and Waldman met through mutual friends in 2018 and were engaged a year-and-a-half later. In May, Miller tested positive for
COVID-19. Her diagnosis was initially concealed until Trump identified her publicly. According to
The New York Times, Trump was "annoyed" that Miller had contracted the virus and imposed
mask requirements for
White House employees. That month, Pence promoted Miller to as his communications director. Near the conclusion of Trump's term—and as Trump publicly feuded with Pence, culminating in calls for violence against him by participants of the
January 6 Capitol attack—Miller was on maternity leave.
Post-government activities and Musk (2021–2025) Miller remained with Pence after the
inauguration of Joe Biden. According to
The New York Times, Miller was still employed by Pence to collect healthcare benefits, but was later fired over her husband's continued work with Trump. In February 2023, several allies of
Florida governor
Ron DeSantis and Pence established an organization to pressure Republican state lawmakers to approve infrastructure projects. Miller was appointed to lead its press operation. In September, she joined
Phil Cox's P2 Public Affairs as a principal. Miller ran a
super PAC for
Jack Ciattarelli, a Republican candidate in the
2025 New Jersey gubernatorial election, alongside
Kellyanne Conway. In Trump's
second presidential transition, Miller served as the media representative for
Robert F. Kennedy Jr., Trump's nominee to serve as
secretary of health and human services. She told
Politico that she did not intend to serve in Trump's
second term. In December 2024, Trump announced that Miller would work for the
Department of Government Efficiency, an initiative to cut government spending heralded by
Elon Musk. Through P2 Public Affairs, she served as a liaison between Musk's team and Trump's team. Miller continued to work for Kennedy handling communications as he neared the confirmation process. She led communications for the Department of Government Efficiency. Miller was employed at the Department of Government Efficiency as a
special government employee, a position that allowed her to continue working for P2 Public Affairs and the lobbyist Jeff Miller, though federal law mandated that she and Musk leave their positions by the end of May. After
The Wall Street Journal reported that Miller was still working for P2 Public Affairs, she took a leave of absence from the company that month. Miller additionally advised Musk at the Department of Government Efficiency. As the initiative's communications director, she ignored reporters that used pronouns in their signatures. According to
The New York Times, Miller threatened
Leland Dudek, the acting
commissioner of Social Security, not to contradict the false figure that scammers were responsible for forty percent of calls to the
Social Security Administration. In May, Musk and Miller left the Trump administration after their tenures as special government employees expired. Days later, Trump and Musk
publicly feuded, the Millers's loyalties—Stephen having worked for Trump and Katie having worked for Musk—came into question. According to
The New York Times, Miller intended to remain with Musk after he announced he was leaving the Department of Government Efficiency. Questions surrounding the perceived alliances between Musk and the Millers continued after Musk publicly rebuked
Grok, a chatbot developed by his company,
xAI, for verifying a false post of Musk taunting Stephen. In July, rumors from some Republicans emerged that Katie had distanced herself from Musk after she changed her banner from a
SpaceX rocket to an image of her and her children, and after Musk unfollowed Miller on
X. Miller told
Reuters that she continued to work for him.
Podcasting (2025–present) In August 2025, Miller announced that she would start a weekly podcast for Republican women. She told
Axios that her podcast, titled
The Katie Miller Podcast, was not exclusively focused on politics and compared it to the podcast
Call Her Daddy (2018–present) with a conservative slant. Her initial guests included vice president
JD Vance, the former boxer
Mike Tyson, and the sports announcer
Sage Steele. Following the
2026 United States intervention in Venezuela and Trump's vow to
annex Greenland, Miller posted an image of the map of
Greenland with the American flag overlaid within the borders. The post received criticism from
Denmark's ambassador to the U.S., Jesper Møller Sørensen, and Greenland's prime minister,
Jens-Frederik Nielsen. ==References==
