Trump's Latest AI Safety Chief Resigns After Three Months

My take: Three directors of the US federal AI standards agency in four months. David Sacks left his White House AI czar role in March. Collin Burns lasted less than a week at CAISI in April (he was pushed out because of his prior work at Anthropic). Chris Fall, the third, just resigned after three months, with the Commerce Department giving no reason.

This is not just personnel turnover. CAISI is the agency responsible for defining the technical AI safety standards for the US federal government, and its instability has concrete consequences: which tests get done, which risks get prioritized, and what gets published publicly. Leaving that seat empty is not a bureaucratic detail.

Meanwhile, the market does not wait. The most capable models in history are arriving right now, and the question of who sets the rules in Washington still has no stable answer. NIST director Arvind Raman is stepping in as acting director.

For companies operating in regulated sectors or depending on federal contracts: is US regulatory uncertainty factored into your AI planning?
