President-elect Trump said Sunday that Katie Miller, who served in Trump’s previous administration, will join the inaugural "Department of Government Efficiency" (DOGE), a new advisory board headed by Vivek Ramaswamy and Elon Musk that aims to slash excessive government spending and regulations. Miller is also married to incoming deputy chief of staff Stephen Miller, a longtime ally and backer of Trump’s. “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 wrote in a post on his Truth Social platform. “Katie is a deeply experienced communications professional respected by all. Congratulations to Stephen and Katie!” Trump continued. Miller was former Vice President Mike Pence’s press secretary and served as deputy press secretary for the Department of Homeland Security during Trump’s first administration. She has also worked for Sen. Steve Daines (R-Mont.) as press secretary and former Sen. Martha McSally (R-Ariz.) as her communications director.
