Anthropic Names First Global Affairs Chief Amid Growing Global AI Policy Push

Anthropic has hired Mariano-Florentino "Tino" Cuéllar as its first chief global affairs officer. The appointment places a former California Supreme Court justice and Obama White House adviser who most recently ran a major foreign policy think tank at the center of what has become one of the most politically fraught relationships in the technology industry: the one between Anthropic and the U.S. government.

Cuéllar will report to Anthropic President Daniela Amodei and work out of the company's San Francisco headquarters. His job is to manage the company's relationships with government officials in the United States and across the growing list of countries where Anthropic operates. He is taking a leave of absence from Stanford Law School to do it.

The timing is not subtle.

Anthropic's relationship with Washington has deteriorated sharply over the past year. In March, the Pentagon designated the company a supply-chain risk after Anthropic refused to allow its Claude AI models to be used for autonomous weapons or mass surveillance of Americans. Anthropic sued, and that case is still working through the courts. A federal appeals court in Washington, D.C., denied Anthropic's request to temporarily block the blacklisting in April, though it acknowledged the company was likely to suffer harm and agreed to expedite proceedings. More recently, the Trump administration imposed export controls that temporarily barred Anthropic from selling its most advanced models, Mythos 5 and Fable 5, to foreign buyers on national security grounds.

Cuéllar, in short, is walking into a job that did not exist six months ago because six months ago Anthropic did not need a full-time diplomat. Now it does.

The Pick

The choice of Cuéllar signals what kind of fight Anthropic expects. He is not a Silicon Valley lobbyist. He is a consensus builder with deep institutional credentials, and the company appears to be betting that the path forward requires someone who can speak the language of national security and international governance simultaneously.

His resume supports that reading. Cuéllar served as a special assistant in the Obama White House, working on regulatory policy and public safety. He sat on President Biden's Intelligence Advisory Board. He was a justice on the California Supreme Court. Most recently, he served as president of the Carnegie Endowment for International Peace, the Washington-based foreign policy think tank, stepping down from that role in July. At Carnegie, he co-chaired a bipartisan task force on U.S. national security and nuclear proliferation, a domain some AI industry leaders have pointed to as a model for governing AI's dual-use risks.

He also co-led a 2025 study that informed the passage of California's SB 53, the first U.S. law specifically focused on AI safety. The legislation protects AI whistleblowers, requires high-revenue developers to report on safety standards and incidents, and carries a maximum fine of $1 million per violation. Anthropic endorsed that bill.

Oren Cass, founder of the conservative think tank American Compass and a friend of Cuéllar's, offered a window into how the hire might play across the aisle. He described Cuéllar as pragmatic and open-minded to the Trump administration's positions. "His approach will be one that provokes good deliberative policymaking with the administration," Cass said.

A Complicated Departure

There is an additional wrinkle. Cuéllar has been a member of Anthropic's Long-Term Benefit Trust since January. The Trust is an independent four-person body that exists to hold the company accountable to its public benefit mission, with influence over board governance and corporate direction. Cuéllar is stepping down from the Trust to take the new role, and the organization is now looking for a replacement.

The move from independent overseer to company executive is notable. It collapses a layer of institutional separation that was, in principle, designed to keep Anthropic's mission-driven commitments distinct from its business operations. Whether Cuéllar's departure weakens that structure depends on who replaces him.

The Bigger Picture

Cuéllar joins Anthropic at a moment when governments worldwide are debating the impact of AI on economic policy and national security with increasing urgency. On the same day Anthropic announced the appointment, White House officials met with representatives from several major AI companies to discuss an unpublished framework for regulating new models and testing their cybersecurity protections.

"Policymakers in the U.S. and around the world are increasingly realizing that we are at a critical inflection point," Cuéllar said in a statement. He called for democracies to set the terms on which AI advances and described Anthropic as the most consequential place to be doing that work right now.

Daniela Amodei framed the hire in terms of character. She described Cuéllar as someone who has spent his career helping public institutions respond to periods of change with thoughtfulness and pragmatism. She said he would partner with governments and civil society groups as they engage with the risks and opportunities of advanced AI.

The company declined to make Cuéllar available for an interview.

What is clear is that Anthropic has decided political relationships are no longer a side function. They are a core business requirement. The Pentagon blacklist and the export controls on Mythos 5 and Fable 5 are actively shaping what Anthropic can sell and who can buy it. Hiring a former Supreme Court justice who ran the Carnegie Endowment and served in three presidential administrations to manage those relationships is a proportional response to a set of problems that are no longer hypothetical. They showed up in court filings and export restrictions months ago.
