The claim is false because the provided sources show that Marco Rubio accused Cuba of cultivating or supporting radical-left networks, but they do not establish that Cuba funded and organized specific radical left-wing protests in the United States.
Marco Rubio accuses Cuba of helping fund & organize radical left-wing protests in the U.S.

Marco Rubio accuses the Cuban Regime of helping shape the far left in the US and the West
Source: voz.us
Key Evidence
Multiple July 2026 reports say Rubio characterized Cuba as a long-term sponsor of radical leftism and as maintaining intelligence or ideological networks.
None of the supplied excerpts documents specific Cuban funding for, or operational coordination of, U.S. Protests.
The available evidence therefore establishes an accusation about ideological influence, not the concrete protest-funding and organizing claim.
What the Evidence Shows
The search results consistently report a July 2026 allegation by Secretary of State Marco Rubio that the Cuban government has promoted radical leftism, Marxism, or far-left movements through intelligence and ideological networks. Several sources describe this as a broad historical or ideological influence claim spanning decades and multiple countries.
However, the wording in the input is more specific: it says Cuba helped fund and organize protests in the United States. The provided material does not identify particular protests, financial transfers, organizers, operational instructions, or documentary evidence demonstrating that Cuba directly funded or organized such events.
The sources also differ in framing:
- –8 report or repeat Rubio’s allegations, generally presenting them as claims by the State Department or Rubio rather than independently verified findings.

- reports an accusation involving Iran, Cuba, and Antifa, but the supplied excerpt still does not provide evidence of Cuba organizing particular U.S. Protests.

- provides critical context, describing the State Department’s presentation as framing Cuba as a major threat through left-wing groups.

Thus, the evidence supports the narrower statement that Rubio accused Cuba of helping build or influence far-left movements. It does not substantiate the stronger claim that Cuba helped finance and organize radical left-wing protests in the United States.
