The lawyer behind Julian Assange set to defend Nicolas Maduro — who is Barry Pollack?

When news broke that Barry Pollack, the American lawyer best known for helping secure Julian Assange’s exit from a years-long legal nightmare, would now defend Nicolas Maduro, it immediately set off alarms across diplomatic and legal circles. Pollack, a partner at Harris, St. Laurent & Wechsler, brings decades of elite white-collar defense experience to a case defined by charges of narco-terrorism, money laundering, and a $15 million federal bounty.

The trial follows an unprecedented "large-scale strike" by U.S. forces in January 2026. President Donald Trump announced that Maduro and his wife, Cilia Flores, were captured in Caracas and flown to the United States. On Monday, January 5, Maduro pleaded not guilty in a Manhattan federal court. Dressed in prison garb with his feet shackled, the 63-year-old maintained his innocence, stating through an interpreter, "I am still president of my country."

Pollack’s involvement signals a sophisticated defense strategy focused on sovereign immunity and the legality of extraterritorial capture. With the Department of Justice alleging that Maduro led the "Cartel of the Suns" to flood American streets with cocaine, the courtroom battle represents the most significant prosecution of a foreign head of state since Manuel Noriega.

Barry Pollack’s transition from WikiLeaks to the Maduro defense

Barry Pollack is not a stranger to cases that pit individuals against the full might of the United States government. For years, he served as the primary legal shield for WikiLeaks founder Julian Assange. Pollack was the architect of the delicate 2024 plea deal that allowed Assange to plead guilty to a single felony count under the Espionage Act in a U.S. court in Saipan.

That deal ended a 14-year legal odyssey and allowed Assange to return to Australia. By successfully navigating the intersection of national security law and First Amendment protections, Pollack established himself as a premier negotiator in cases with heavy political overtones.

The decision to represent Nicolás Maduro marks a pivot from digital transparency advocacy to the defense of a deposed head of state. Maduro is currently facing a 2020 indictment that accuses him of conspiring with the FARC (Revolutionary Armed Forces of Colombia) to use cocaine as a weapon against the United States.

Pollack’s entry into the case suggests that the defense will not merely be about the facts of drug trafficking. Instead, it will likely involve a deep dive into the "act of state" doctrine and whether a U.S. court has the jurisdiction to try a man who claimed the presidency of a sovereign nation.

Pollack’s career is built on winning "unwinnable" cases, such as his 2006 acquittal of Michael Krautz in the Enron scandal, proving his ability to humanize defendants in the eyes of a jury even amidst intense public scrutiny.

Geopolitical context of the Maduro capture and U.S. charges

The trial of Nicolás Maduro is the culmination of years of escalating tension between Washington and Caracas. In March 2020, the U.S. Department of Justice took the rare step of indicting a sitting head of state. They alleged that Maduro and his inner circle operated a narco-terrorism partnership for over two decades. The U.S. government claims that Maduro oversaw the shipment of hundreds of tons of cocaine through Venezuelan airspace and maritime routes.

Following the disputed 2024 Venezuelan elections and subsequent civil unrest, the U.S. maintained that Maduro’s legitimacy had evaporated. This set the stage for the 2026 military intervention and his subsequent extradition to New York.

Pollack enters the fray as Venezuela remains in a state of political transition. The prosecution’s case relies heavily on testimony from former Venezuelan officials and intercepted communications. Prosecutors argue that the "Cartel of the Suns"—a group of high-ranking Venezuelan military officers—worked under Maduro’s direct command to facilitate the transit of drugs from Colombia to the United States.

Pollack’s challenge will be to discredit these witnesses, many of whom are cooperating with the U.S. government in exchange for reduced sentences. He will likely argue that the charges are politically motivated "regime change" tactics disguised as criminal prosecution. This defense requires a lawyer who understands how to handle sensitive Grand Jury evidence and classified briefings, areas where Pollack has extensive experience.

The courtroom proceedings are presided over by U.S. District Judge Alvin Hellerstein. At 92 years old, Hellerstein is a pillar of the New York legal community with a reputation for being no-nonsense and fiercely independent. Having been appointed by President Bill Clinton in 1998, Hellerstein has overseen some of the most complex litigations in American history. He managed the massive tort litigation following the September 11 attacks and recently handled cases involving President Donald Trump’s hush-money payments.

Judge Hellerstein has already indicated that he intends to keep the case moving efficiently. He has a history of demanding clarity from both prosecutors and defense attorneys.

In recent hearings, Hellerstein emphasized that the court’s role is to determine criminal guilt or innocence, not to settle foreign policy disputes. For Barry Pollack, this means he must tailor his defense to meet the rigorous standards of a judge who is famously difficult to sway with emotional or purely political arguments.

The core of Pollack’s defense is expected to center on the concept of head-of-state immunity. Under international law, sitting leaders are generally protected from the jurisdiction of foreign courts. While the U.S. government argues that it stopped recognizing Maduro as the legitimate president years ago, Pollack may argue that the de facto control Maduro exercised over Venezuela grants him certain legal protections.

Pollack has previously demonstrated this capability in his work for Chelsea Manning and in various civil rights exonerations, where he challenged the very foundations of the government's legal positions.

Furthermore, Pollack will likely scrutinize the methods used to bring Maduro to New York. If the defense can prove that the capture violated international treaties or the sovereignty of the Venezuelan people, it could lead to motions to dismiss the indictment.

This "legal chess" is what Pollack is known for in Washington and New York legal circles. By focusing on the procedural integrity of the case, he can fight the government on multiple fronts simultaneously.

The Maduro trial is not just a criminal case; it is a test of how the American legal system handles a deposed world leader. With Barry Pollack at the helm of the defense, the U.S. government faces an adversary who knows exactly how to find the weaknesses in a federal prosecution’s armor.
