Anthropic Meets House Homeland Security Behind Closed Doors as Supply Chain Phase-Out Begins

Anthropic co-founder Jack Clark briefed bipartisan House Homeland Security Committee members in a closed session focused on model distillation risks and export controls, barely touching the company's ongoing lawsuit over its Pentagon supply chain risk designation. The session is part of a series the committee is convening on DHS technology acquisition. Anthropic is simultaneously suing the government while opening a parallel congressional track to contest the designation.

Analysis
Prior IC brief noted the Mayer Brown legal analysis of the supply chain designation's effective date. This closed-door briefing signals Anthropic is pursuing a legislative override strategy alongside its judicial challenge.
