Anthropic has named Mariano-Florentino Cuéllar as its new global affairs chief, tasking the former California Supreme Court justice with easing strained relations between the artificial intelligence firm and the administration of U.S. President Donald Trump.
The appointment comes as the company faces a challenging political environment in Washington, where the Republican administration has moved to blacklist Anthropic’s AI systems and impose controls around their use earlier this year. Cuéllar’s central mandate is to find common ground with policymakers amid a widening rift over AI regulation.
Anthropic, the maker of the Claude family of AI models, has positioned itself as a proponent of stronger safety guardrails and government oversight of advanced artificial intelligence, a stance that has at times placed it at odds with an administration favouring a lighter-touch, deregulatory approach to the fast-moving sector.
The friction underscores the increasingly high stakes for AI developers as the technology becomes intertwined with national security, economic competitiveness, and public policy. Companies once focused primarily on research now find themselves negotiating directly with governments over export controls, procurement, and safety standards.
Cuéllar brings a background spanning law, public policy, and governance to the role. His experience on California’s highest court and in policy circles is expected to help Anthropic engage more effectively with regulators and lawmakers at a delicate moment for the industry.
The company has expanded rapidly in recent years, developing systems capable of executing complex multi-step tasks and drawing significant investment. That growth has heightened scrutiny of how its models are deployed and governed.
The tensions also reflect a broader global contest over AI leadership, with the United States and China competing for dominance in the technology while grappling with how to regulate it. Firms operating across borders must balance commercial ambitions against a patchwork of national policies.
Anthropic has framed its regulatory posture as consistent with its founding emphasis on AI safety, arguing that responsible development requires cooperation with governments rather than resistance to oversight.
The company is expected to lean on Cuéllar to rebuild channels of communication with the administration and to shape emerging policy frameworks. How successfully he can bridge the divide may influence Anthropic’s access to government contracts and its standing in a rapidly consolidating market.
