Katie Miller, longtime Trump administration spokeswoman and wife of White House Deputy Chief of Staff Stephen Miller, is stepping down from her role at the Department of Government Efficiency (DOGE) to begin a new position working with tech mogul Elon Musk. The move comes just days after Musk concluded his service in President Donald J. Trump’s administration.

According to The Daily Mail, Miller will take on a media-focused role at Musk’s companies, SpaceX and Tesla. Her departure marks a notable shift as DOGE, a signature initiative under President Trump’s second term, continues to evolve.

Miller was appointed to DOGE’s advisory board in December 2024 and played a key communications role in the agency’s mission to root out government waste, fraud, and abuse.

She’s not the only high-profile departure. Two other senior officials, attorney James Burnham and Musk confidant Steve Davis, are also exiting their posts this week, as confirmed by ABC News.

Davis, a veteran Musk associate who previously served at SpaceX, the Boring Company, and X, held the title of Chief Operating Officer at DOGE, per The Hill. Burnham, who served as general counsel, brings a strong legal pedigree, having clerked for Supreme Court Justice Neil Gorsuch.

Their terms as special government employees expired after 130 days of service—a temporary but intense tenure supporting President Trump’s vision to streamline Washington and rein in bureaucratic excess.

Despite their exit, Musk made it clear during a White House press conference that DOGE’s mission is far from over.

“This is not the end of DOGE, but really the beginning,” Musk said confidently. “The DOGE team will only grow stronger… I am confident that over time, we will see $1 trillion dollars of waste and fraud reduction.”

Katie Miller brings deep experience from the first Trump presidency, where she held several communications roles. She and Stephen Miller married in 2020 and now share three children.

However, the departure was not without tension. In a CBS teaser released Tuesday, Musk criticized the administration’s latest spending package.

“I was disappointed to see the massive spending bill, frankly, which increases the budget deficit, not just decreases it, and undermines the work that the DOGE team is doing,” Musk stated.

He added pointedly:

“I think a bill can be big, or it can be beautiful, but I don’t know if it can be both, in my personal opinion.”

That same day, Stephen Miller offered a pointed response on X (formerly Twitter), clarifying the legislative constraints around the DOGE initiative:

“DOGE cuts are to discretionary spending. (Eg the federal bureaucracy). Under senate budget rules, you cannot cut discretionary spending (only mandatory) in a reconciliation bill,” Miller wrote.

He further explained that such reductions must be accomplished through rescissions packages or the standard appropriations process.

While political disagreements between allies are not uncommon, the mutual commitment to shrinking the size and scope of the federal government remains strong. With a continued focus on transparency and accountability, President Trump’s administration is forging ahead with its reform agenda—even as key players like Katie Miller and Elon Musk pivot to new frontiers.
