Katie Miller, born Katie Waldman, is one of a small group of former Trump White House staff who moved between communications, immigration policy and, more recently, the Department of Government Efficiency (DOGE). She is married to Stephen Miller, the Trump policy adviser, which has shaped much of her public profile.

Career background

Miller began her communications career on Capitol Hill, working for senators including Martha McSally. She joined the first Trump administration as a press secretary at the Department of Homeland Security under Kirstjen Nielsen, then moved to the office of Vice President Mike Pence, where she served as press secretary from 2019.

During the COVID-19 response in 2020 she was the lead communications voice for the White House Coronavirus Task Force chaired by Pence, a role that placed her in daily contact with the Washington press corps and put her at the centre of several disputes over messaging.

Return to Trump-world

After the 2020 election Miller worked in the private sector and on Republican campaigns. With Donald Trump's return to office in January 2025 she rejoined his orbit, this time linked to the Department of Government Efficiency initiative led by Elon Musk and Vivek Ramaswamy, where she has been described in reporting as a senior adviser handling external communications.

Public profile and podcast

In 2024 and 2025 Miller has been a regular guest on conservative-leaning podcasts and has co-hosted limited-run series herself, principally on themes of family, faith and Washington politics. Her marriage to Stephen Miller, one of the most polarising figures in the Trump policy operation, is a recurring subject of interview coverage.
