All macro-cases, as Zapatero's case is pointed out, have their concrete origin in a key character. There is usually an individual who allows the investigating judge to turn the investigation around, a kind of patient zero. In the case affecting the former Spanish president, this figure is the Venezuelan Rodolfo Reyes Rojas and the lever necessary for Judge José Luis Calama to reach him has been the United States, as is evident from the report by the UDEF of the National Police. That is to say, the investigation into Zapatero did not begin with a complaint from Manos Limpias –as the Spanish government initially stated–, but rather the evidence now in the hands of the National High Court comes from the agency Homeland Security Investigations (HSI), still during the Biden administration. Calama has issued an international arrest warrant against Reyes and his wife, Aurora López, for crimes of influence peddling, misappropriation, membership in a criminal organization, and money laundering.
