Anthropic Sends Staff to Washington as Fable and Mythos Export Control Standoff Escalates

This is a developing story. NCT covered the original export control directive on June 13 and Amazon’s role in surfacing security concerns on June 14. This article covers Monday’s escalation.

Senior Anthropic staffers traveled to Washington, D.C., on Monday to meet directly with Trump administration officials over the export control directive that forced the company to take its most advanced AI models offline, according to CNBC, citing a source close to the company.

The directive, issued Friday June 13, cited “national security authorities” and ordered Anthropic to suspend access to Fable 5 and Mythos 5 “by any foreign national, whether inside or outside the United States,” according to Anthropic’s public statement referenced by CNBC’s earlier reporting. Anthropic disabled access to both models for all customers to ensure compliance.

The Pentagon Thread

The standoff comes against the backdrop of a longer dispute between Anthropic and the U.S. government. The Department of Defense labeled Anthropic a supply chain risk in March, banning defense contractors from using the company’s technology. Anthropic sued the Trump administration to reverse the designation, and that litigation remains ongoing, according to CNBC.

Defense Secretary Pete Hegseth used the latest export control action to reinforce the Pentagon’s position. In a post on X on Saturday, Hegseth wrote that “every passing day” proves why blacklisting Anthropic was “the right move,” per CNBC.

What Changed Monday

The in-person meetings represent a shift from Anthropic’s prior approach. Administration officials have claimed the company has not engaged seriously to date, according to CNBC’s reporting. By sending senior technical staff to Washington, Anthropic appears to be treating the directive as a negotiation rather than a legal fight, at least in parallel with its existing lawsuit against the DOD designation.

The directive’s scope is notable: it applies to any foreign national regardless of location, meaning even non-U.S. employees of American companies using Fable 5 or Mythos 5 would fall under the restriction. For enterprise customers that integrated these models into production systems, the abrupt shutdown created immediate operational disruption that Anthropic is now racing to resolve through direct government engagement.
