Senators Banks and Grassley Demand AI Companies Address Chinese Espionage Threat to Model Weights

Analysis
The Banks-Grassley letters, corroborated by an Axios exclusive with apparent embargoed Senate access, mark the first cross-committee demand that AI companies account for model weights as a targeted counterintelligence vulnerability. The Google engineer conviction forecloses dismissal as speculative. Disclosure by at least one major AI firm of a Chinese government-linked incident within six months is a roughly even chance, given structural incentives to suppress absent legal compulsion and congressional letters' lack of subpoena power. The May 26 deadline will produce either actionable disclosures or lawyered non-answers that build a record for escalation. The letters may instead reflect domestic political positioning by both chairmen ahead of defense authorization negotiations.
