Trump's AI Safety Agency Head Resigns After Three Months

Axios·high signal

Dr. Chris Fall, director of the Commerce Department's Center for AI Standards and Innovation (CAISI), resigned on July 20 after being appointed in April; no reason was given. NIST director Arvind Raman becomes acting CAISI director. The role has become a revolving door since David Sacks stepped down as White House AI and crypto czar in March and was never replaced — leaving the agency running the classified frontier-model benchmarking process without permanent leadership.
