Former Army Secretary Dan Driscoll joins OpenAI as national security adviser, stoking AI–Pentagon concerns
Dan Driscoll, who became U.S. Army Secretary at 38, has taken a new post at OpenAI as senior adviser on national security modernization, a job the company created for him after years of close contact between top tech firms and the Pentagon.
A year after publicly honouring big tech executives for their role in U.S. defence, the Pentagon’s youngest Army Secretary has gone to work for one of them.
Dan Driscoll, appointed Army Secretary at age 38, has joined OpenAI as senior adviser on national security modernization. OpenAI created the role specifically for him, signalling how closely the company is aligning its work with military needs and how valuable it sees his experience inside the Pentagon.
In June 2025, while still serving as Army Secretary, Driscoll awarded lieutenant colonel insignia to top executives at OpenAI, Meta and Palantir in a ceremony that highlighted the depth of cooperation between the Army and leading technology firms. The gesture cast those companies as partners in shaping the future of military operations.
His move to OpenAI has sharpened long‑running questions in Washington about the “revolving door” between senior defence officials and the companies that supply them, this time focused on artificial intelligence rather than traditional weapons manufacturers.
In his new role, Driscoll is expected to advise OpenAI on how to design tools for missions such as threat analysis, planning and decision support, drawing on his understanding of how commanders think and what constraints they face. That input could influence the systems that appear in future Pentagon procurement programmes.
The appointment also raises oversight issues. Driscoll has had access to classified assessments of U.S. and foreign capabilities and insight into the Army’s modernization budgets. While strict rules govern classified information, drawing a clear line between general experience and specific inside knowledge can be difficult when a former official helps a company position itself for large defence contracts.
From a strategic perspective, the hire underlines how quickly AI developers and the U.S. military are converging. Tech firms like OpenAI increasingly provide software that militaries see as central to gaining an edge, while the Pentagon is becoming a major customer whose requirements and ethical rules will shape AI products.
Other governments will be watching. European officials debating how to regulate military AI may point to Driscoll’s move as a reason to demand tighter rules on post‑government employment. In capitals that see the United States as a rival, the appointment reinforces the view that American advances in AI are being tied directly to military power.
The most telling signs of how this plays out will be future contract awards and policy documents. If OpenAI features prominently in new Pentagon programmes connected to Driscoll’s portfolio, calls for longer cooling‑off periods and more transparency around AI lobbying are likely to grow. At the same time, internal U.S. doctrine on autonomous systems and human oversight will show how much weight industry voices like Driscoll’s carry in setting the boundaries for the technology they now help to sell.
