Cliver Alcalá began to reside in Barranquilla, Colombia from 2018 until his decision to surrender to US authorities in March 2020.

On 26 March 2020, Alcalá assumed responsibility for "a military operation against the Maduro dictatorship", including a shipment of weapons captured in Colombia, stating that the United States, Colombia and Juan Guaidó officials had signed an agreement to support their efforts to overthrow President Maduro.
Guaidó denied knowledge of the event while United States Special Representative to Venezuela Elliott Abrams described Alcalá's statement as "despicable and quite dangerous".

Alcalá is reported to have played a role in planning the unsuccessful Macuto Bay raid, which took place after he was extradited to the United States.
