Trump’s latest AI czar has already resigned

Chris Fall, the director of the Center for AI Standards and Innovation, has resigned just three months after his appointment. This marks the latest in a series of leadership departures within the agency as the Trump administration navigates AI oversight and cybersecurity policy.
Why it matters
Frequent turnover in key AI regulatory roles creates uncertainty regarding the U.S. government's approach to AI safety and technical standards.
Chris Fall, the director of the Center for AI Standards and Innovation (CAISI), has resigned, the agency confirmed to multiple news outlets.
He was appointed just three months ago after the last appointee, Collin Burns, left in less than a week, The Washington Post reported at the time. Burns was reportedly “pushed out” of the job in April because he previously worked for Anthropic and the Trump administration had been battling with the company, sources told the Post.
No reason was given for Fall’s departure. Prior to leading CAISI, Fall was the director of the Department of Energy’s Office of Science during the first Trump administration and had been the acting director of the DOE’s Advanced Research Projects Agency-Energy. He worked in the DOE’s Office of Naval Research (ONR) prior to that.
