Amy Gleason, the acting administrator of the U.S. DOGE Service, isn't a household name. But as Elon Musk’s effort to dramatically reduce the federal government faces legal challenges, the nurse-turned-programmer has been thrust into the spotlight.

Amy Gleason, a nurse turned health care technology consultant, was recently named the acting administrator for DOGE. How much control she has at DOGE is unclear.

The acting administrator of the organization that is pushing for sweeping budget cuts across federal agencies is a low-profile executive who has expertise in health care technology.

In his address to Congress Tuesday, President Donald Trump made clear that Elon Musk is in charge of the Department of Government Efficiency. Yet government lawyers have argued in court that Gleason and not Musk is the agency’s leader.
