The officials warned Cabello, 62, against using the security services or militant ruling-party supporters he oversees to target the country's opposition, four sources said. That security apparatus, which includes the intelligence services, police and the armed forces, remains largely intact after the January 3 US raid, Reuters reported.
Cabello is named in the same US drug-trafficking indictment that the Trump administration used as justification to arrest Maduro, but was not taken as part of the operation.
The communication with Cabello, which has also touched on sanctions the US has imposed on him and the indictment he faces, dates back to the early days of the current Trump administration and continued in the weeks just prior to the US ouster of Maduro, two sources familiar with the discussions said. The administration has also been in touch with Cabello since Maduro's ouster, four of the people said.
The communications, which have not been previously reported, are critical to the Trump administration's efforts to control the situation inside Venezuela. If Cabello decides to unleash the forces that he controls, it could foment the kind of chaos that Trump wants to avoid and threaten interim President Delcy Rodriguez's grip on power, according to a source briefed on US concerns.
It is not clear if the Trump administration's discussions with Cabello extended to questions about the future governance of Venezuela. Also unclear is whether Cabello has heeded the US warnings. He has publicly pledged unity with Rodriguez, whom Trump has so far praised.
While Rodriguez has been seen by the US as the linchpin for US President Donald Trump's strategy for post-Maduro Venezuela, Cabello is widely believed to have the power to keep those plans on track or upend them.
The Venezuelan minister has been in contact with the Trump administration both directly and via intermediaries, one person familiar with the conversations said.
All of the sources were granted anonymity to speak freely about sensitive internal government communications with Cabello.
Cabello has long been seen as Venezuela's second most powerful figure. A close aide of late former President Hugo Chavez, Maduro's mentor, he went on to become a long-time Maduro loyalist, feared as his main enforcer of repression. Rodriguez and Cabello have both operated at the heart of the government, legislature and ruling socialist party for years, but have never been considered close allies of each other.
