WASHINGTON () – President-elect Donald Trump on Sunday named Katie Miller, who served in Trump’s first administration and is the wife of his incoming deputy chief of staff, as one of the first members of an advisory board to be led by billionaire allies Elon Musk and Vivek Ramaswamy that aims to drastically slash government spending, federal regulations and the federal workforce.

Miller, wife of Trump’s designated homeland security adviser Stephen Miller, will join Trump’s Department of Government Efficiency (DOGE), an informal advisory body that Trump has said will enable his administration to “slash excess regulations, cut wasteful expenditures, and restructure Federal Agencies.”

“Katie Miller will soon be joining DOGE! She has been a loyal supporter of mine for many years, and will bring her professional experience to Government Efficiency,” Trump posted in a message on his social media platform Truth Social.

Musk and Ramaswamy recently revealed plans to wipe out scores of federal regulations crafted by what they say is an anti-democratic, unaccountable bureaucracy, but have yet to announce members of the DOGE team. Musk has said he wants to slash the number of federal agencies from over 400 to 99.

Katie Miller had served in the first Trump adminstration as deputy press secretary for the Department of Homeland Security and as press secretary for former Vice President Mike Pence.

She is currently a spokesperson for the transition team for Trump’s designated Health and Human Services secretary, Robert Kennedy Jr.
