Anthropic Hires Ex-Obama Aide as Its First Global Affairs Chief After Pentagon Blacklist Fight

Anthropic just handed its Washington problem to a new guy. On Tuesday, August 4, the company named Mariano-Florentino Cuellar, who goes by Tino, as its first chief global affairs officer, according to Reuters. He'll report directly to Anthropic President Daniela Amodei out of the company's San Francisco headquarters.

His job: keep Anthropic from getting steamrolled by the U.S. government while it tries to expand into other countries too. That's a tall order given the last several months.

The Mess He's Walking Into

The Pentagon blacklisted Anthropic's technology earlier this year, designating the company a supply-chain risk, according to TheNextWeb. Why? Anthropic refused to let its Claude models be used for autonomous weapons or mass surveillance of Americans. Anthropic sued the government over it. That case is still in court.

Then the Trump administration slapped export controls on Anthropic's top-tier models, citing national security concerns, according to TheNextWeb. The ban lasted roughly three weeks before Anthropic agreed to a set of security commitments and got it lifted.

So Cuellar isn't walking into a ribbon-cutting. He's walking into active litigation and a company that just got export-banned by its own government.

Who Is This Guy

Cuellar's resume reads like a Democratic Party fever dream. He was a special assistant in Barack Obama's White House. He sat on the California Supreme Court. He ran the Carnegie Endowment for International Peace until this past July, where he co-chaired a task force on nuclear proliferation and national security.

That nuclear angle matters. Some AI industry leaders have pointed to Cold War-era arms control as a model for managing AI risk, and Cuellar's background fits that framing neatly.

He's also been on Anthropic's Long-Term Benefit Trust since January, an independent four-person body meant to keep the company honest about its stated public benefit mission. He's stepping down from that trust to take the new job, and Anthropic now has to find a replacement for that seat.

One more data point: a 2025 study Cuellar co-led helped shape California's SB 53, a law that protects AI whistleblowers, forces high-revenue AI developers to report on safety standards and incidents, and carries fines up to $1 million per violation. Anthropic publicly endorsed that bill. So Cuellar isn't some neutral referee walking in cold. He's a guy whose prior work directly fed into the regulatory framework Anthropic wants applied to the industry, including its competitors.

The Pitch to Conservatives

Oren Cass, founder of the conservative think tank American Compass, told Reuters that Cuellar will be "open-minded" to the Trump administration's positions and eager to find the root of any disagreement. Cass says he's known Cuellar for years and the two have run bipartisan lunch discussions together.

Cass is staking some credibility on the idea that a former Obama aide can actually build a working relationship with a Trump administration that has already blacklisted and export-controlled his new employer.

Whether that pans out is unclear. A guy whose fingerprints are on California AI regulation, who spent a decade in Democratic circles, now has to convince a Republican administration that just fought his company in court and in an export dispute that he's a good-faith broker, not just a smoother-talking version of the same regulatory push.

Cuellar's own statement leans into the stakes rather than the politics. "The choices we make today will determine whether humanity can harness extraordinary possibilities to advance science and improve lives across the world or face enormous risk and growing inequality," he said, according to Reuters. Anthropic declined to make him available for an interview, so there's no further detail yet on how he plans to actually thread the Pentagon lawsuit or the export-control fight.

None of the four outlets covering this reported any indication that Anthropic's underlying legal dispute with the Pentagon is close to resolution, or that the export-control truce is permanent rather than a three-week patch. Both remain live, unresolved fights that Cuellar now inherits on day one.
