David Adler, a Rhodes Scholar with reported ties to Cuba's president, helped organize a transnational convoy that delivered an estimated 40 tons of supplies to Havana and brought Twitch streamer Hasan Piker and hundreds of activists, politicians, journalists and organizers from dozens of countries to Cuba earlier this year. The operation, branded "Nuestra América Convoy" or "Our America Convoy," is now drawing scrutiny from federal investigators.
According to statements made by Piker in online interviews, he reached out to Adler for guidance after President Donald Trump intensified sanctions pressure on Cuba's communist government. "I hit my friend up, David Adler, and I was like, 'What do we do?'" Piker recalled. "And he's like, 'I'm already working on it.'" Treasury Department's Office of Foreign Assets Control recently issued administrative subpoenas to both Piker and CodePink co-founder Medea Benjamin, seeking records related to their Cuba travel, communications and financial activity connected to the convoy, according to sources familiar with the investigation.
What the Right Is Saying
Critics view Progressive International as part of a broader pattern of activist networks that provide political legitimacy to authoritarian regimes. Gelet Martinez Fragela, a Cuban American journalist who investigates the Cuban government's influence in the Western Hemisphere through her website ADNCuba.com, offered sharp criticism of the organization's role.
"What makes Progressive International so dangerous is that, by co-opting progressive values, it provides political legitimacy to authoritarian regimes with longstanding records of repression and gross human rights violations, and whose purpose is to destroy the United States," Martinez Fragela told Fox News Digital. She argued that Cuba has "historically used solidarity groups and activist networks as cover to build alliances, raise funds and maintain power while continuing to embed itself within illicit and anti-democratic networks around the world."
What the Left Is Saying
Progressive activists and defenders of the convoy characterize it as a humanitarian mission rather than a political operation. Supporters argue that delivering 40 tons of supplies to Cubans facing economic hardship represents legitimate solidarity work. They note that Progressive International emerged from a 2018 gathering in Burlington, Vermont, convened by Democratic Sen. Bernie Sanders and former Greek Finance Minister Yanis Varoufakis, who sought to build what they described as an international progressive movement.
Piker himself has pushed back against the investigation, arguing that the "real goal" of Treasury's inquiry is Neville Roy Singham, a Shanghai-based American tech entrepreneur who Piker says funds "political operations" in the United States. The convoy's organizers have not responded to requests for comment from multiple news outlets regarding their connections to Cuban government entities.
What the Numbers Show
Fox News Digital identified 145 nonprofits, labor groups, advocacy organizations and activist collectives operating as part of a network mobilizing in support of the Cuban government and Communist Party of Cuba. These organizations report approximately $1 billion in combined annual revenue.
Progressive International Exchange Inc., Adler's California-based 501(c)(3) nonprofit registered in Calabasas (EIN 93-3021918), reported only $261,039 in annual revenue and $215,772 in net assets on its most recent IRS Form 990. It remains unclear whether this U.S. nonprofit is directly connected to the "Progressive International" coalition based in Athens, Greece, which coordinated the Cuba convoy, conferences and public actions.
The Bottom Line
The Treasury Department investigation centers on whether participants in the Nuestra América Convoy had improper contacts with Cuban government personnel or entities. The subpoenas seek travel records, communications and financial activity related to Cuba operations.
Adler, who attended the 2018 Burlington gathering that launched Progressive International alongside Sanders and Varoufakis, has declined comment through multiple media requests. Congressional Republicans have expressed interest in examining these transnational activist networks as potential foreign influence operations. Watch for whether additional subpoenas are issued or if testimony is sought before House or Senate committees.
