# Amazon CEO reportedly raised Anthropic model concerns before government crackdown > Source: > Published: 2026-06-13 19:11:41+00:00 Amazon CEO Andy Jassy may have been the source of security concerns that led [Anthropic to cut off worldwide access to two models](https://techcrunch.com/2026/06/12/anthropics-safety-warnings-may-have-just-backfired-the-government-has-pulled-the-plug-on-its-most-powerful-ai/) on Friday. The Wall Street Journal reports that [Jassy told Treasury Secretary Scott Bessent and other government officials](https://www.wsj.com/tech/ai/amazon-ceos-talks-with-u-s-officials-triggered-crackdown-on-anthropic-models-dcc90578) that Amazon researchers used Anthropic’s Claude Fable 5 to obtain information that could be used in cyberattacks. The government subsequently imposed an export control ban on the Fable 5 and Mythos 5 models. An Amazon spokesperson told the WSJ that while it’s “not uncommon for governments to seek our counsel on potential security risks,” the company does not disclose “the details of those discussions.” [The Information](https://www.theinformation.com/articles/amazons-jassy-raised-concerns-anthropic-model-trump-crackdown) and [Reuters](https://www.reuters.com/business/retail-consumer/amazon-voiced-concerns-about-anthropic-ai-models-before-us-governments-crackdown-2026-06-13/) similarly reported that Amazon (a [major Anthropic investor](https://techcrunch.com/2026/04/20/anthropic-takes-5b-from-amazon-and-pledges-100b-in-cloud-spending-in-return/)) had shared concerns about the security of Anthropic’s models. David Sacks, who Trump’s former AI czar who now co-chairs the President’s Council of Advisors on Science and Technology, offered his own account of the discussions, [claiming](https://x.com/DavidSacks/status/2065853007619588171) that “a highly credible trusted partner of both Anthropic and the USG […] came forward with [information about] a jailbreak.” Sacks added, “The Admin asked [Anthropic CEO Dario Amodei] to fix the jailbreak or de-deploy the model. Dario refused.”
