The news
Anthropic said on August 4, 2026, that Tino Cuéllar, a former California Supreme Court justice, would join as its first Chief Global Affairs Officer, running policy and government relations worldwide while the company fought a Pentagon supply-chain-risk designation in court.
Cuéllar, whose full name is Mariano-Florentino Cuéllar, will lead Anthropic's work on policy, international engagement and relationships with governments, the company said. He reports to President Daniela Amodei and is based at the San Francisco headquarters, The Next Web reported, and The Harvard Crimson reported that he will take a leave of absence from Stanford Law School.
Cuéllar stepped down as president of the Carnegie Endowment for International Peace in July, according to The Next Web. Anthropic's announcement lists earlier roles as director of Stanford's Freeman Spogli Institute for International Studies and of the Stanford Cyber Initiative, and as a member of the President's Intelligence Advisory Board and the State Department's Foreign Affairs Policy Board. He also co-led California's Frontier AI Working Group, whose 2025 study informed the state's SB 53 AI safety law, The Next Web said.
He had been a trustee of Anthropic's Long-Term Benefit Trust, the independent body that can appoint members of the company's board, since January 2026, and stepped down from it to take the job, Anthropic said. The company had announced former Federal Reserve Chair Ben Bernanke as a trustee on July 9.
"Democracies must set the terms on which this technology advances," Cuéllar said in the announcement. Amodei said no one was better prepared to work alongside governments and civic groups as they weigh advanced AI's risks and opportunities.
The hire came during a standoff with the Trump administration. The Pentagon designated Anthropic a supply-chain risk in March 2026 after the company refused to let Claude be used for autonomous weapons or mass surveillance of Americans, according to The Next Web, and Anthropic filed suits that month in California and Washington, D.C., TechCrunch reported. The Crimson and The Next Web also reported that the administration had temporarily restricted international sales of two of Anthropic's advanced models on national security grounds.

Why CEOs should care
For buyers in government, defense and regulated industries, Anthropic's standing in Washington is a procurement question. TechCrunch reported that when the label was applied, federal agencies, including those outside defense, were ordered to stop working with the company. Contractors and public-sector suppliers should map where Claude sits in their products and workflows, and know what they would need to replace if the label stands.
Boards should read the appointment as a sign that government relations has become a core operating function at frontier AI vendors. Ask AI suppliers who owns policy and export-control exposure, and how quickly they would tell customers if a model faced sales limits abroad; two of Anthropic's advanced models faced temporary international restrictions in 2026, according to the Crimson.
For multinationals, Cuéllar's international mandate matters because model availability can depend on national-security decisions made by governments. Write continuity terms into contracts for markets where you operate, and keep a tested fallback model ready.
The bigger picture
The move also changed Anthropic's governance lineup: Cuéllar went from the independent trust that oversees the company's mission to a management job reporting to the president. His résumé spans a state supreme court, a foreign policy think tank and presidential intelligence and State Department advisory boards, a background suited to a year in which Anthropic's most public fights were with the U.S. government.
What happened next
On August 27, 2026, U.S. District Judge Rita Lin in California ruled that the supply-chain-risk designation was unlawful, finding it amounted to First Amendment retaliation and was arbitrary and capricious, TechCrunch reported. Anthropic said it welcomed the ruling and remained focused on working productively with the government.
On September 25, 2026, a divided D.C. Circuit panel upheld the Pentagon's designation on a separate legal basis by a 2-1 vote, Nextgov/FCW reported. Anthropic said it respectfully disagreed and was considering all options, including further review, while Defense Under Secretary Emil Michael praised the decision. Watch for a request for rehearing by the full D.C. Circuit or a petition to the Supreme Court, the next tests for Cuéllar's team.
What “Fact-checked” means
Fact-checking means testing a story’s facts against the evidence before it is published. This story went through at least two separate checks before this version was published.
- What we checked
- Its names, figures, dates, job titles, quotes and who said what were checked against the story’s sources, including its main source where it could be opened. The headline was checked for accuracy and overstatement.
- How
- A first check reviewed the whole story. If it passed, a second, skeptical check went back to the sources to look for mistakes in the most important facts. If a check flagged the story, it was edited to fix the problems found, and a separate re-check then reviewed the whole story again.
- Who
- The checks are made with our newsroom’s technology tools, as steps kept separate from the writing, under rules set by our editor, Hussein Mukhtar. A story the checks still flag is not published automatically; it is held for the editor, who decides whether it is fixed, published or dropped.
- Archive story
- It was written after the event. Its dates were checked against the date of the event, including the dates of any later developments it reports.
- If something is wrong
- “Fact-checked” does not mean error-free. If a material error is found after publication, we correct the story and add a note saying what changed. Report an error
