Trump’s AI Safety Agency Chief Resigns After Just Three Months Leading CAISI

### Executive Summary Chris Fall resigned as director of the U.S. Center for AI Standards and Innovation three months after appointment, raising uncertainty about the Biden (note: the article references the Trump administration) administration's AI safety, model evaluation, and cybersecurity oversight efforts; Arvind Raman of NIST will serve as acting director. The piece highlights how the leadership gap may complicate development of testing standards and evaluation processes for frontier AI models, and it catalogs potential AI-enabled security risks (automated vulnerability discovery, large-scale phishing/social engineering, malicious code generation, model theft, prompt injection, supply-chain concerns) while noting gaps in coordination with the White House's "Gold Eagle" vulnerability program.
