"We have noticed that he interferes in the elections and we do not allow that because we have principles, very clear values, because we do not want anyone interfering in our elections," he said. "We will not let that happen to a foreign country and a friend like the US."
Correa granted Assange an asylum in 2012 seeking refuge in the London embassy to avoid extradition to Sweden for sexual assault, which he rejects. Correa promoted his rise to power over anti-US vitriol and agreed with Assange after WikiLeaks released highly classified Pentagon materials.
The report quoted hundreds of surveillance documents describing Assange's time in the embassy. The documents describe how Assange met with world-class Russians and hackers at critical moments and acquired powerful new computer and networking hardware to facilitate data transfer just weeks before WikiLeaks received hacked material from Russian employees.
"WikiLeaks's justification for providing truthful information," Correa told CNN. "Sure, but it was all about Hillary Clinton, not about (Donald) Trump, so they did not say the whole truth, and not telling the whole truth is manipulation, and we will not allow that."
WikiLeaks has not responded to multiple requests for comment on exclusive CNN coverage. Assange's lawyers refused to comment.
In the interview on Tuesday morning, Correa dissociated himself from Assange, although he firmly defended his decision to grant asylum to the WikiLeaks founder in 2012.
"Do you know how many times I've spoken to Assange, never, I do not know him," Correa said. "He just interviewed me once when he was working on Skype for Russia Today."
Correa was president of Ecuador from 2007 to 2017 and made a name for himself as the leading US antagonist in Latin America, modeled on the late Venezuelan dictator Hugo Chavez.
"I'm much closer to Hillary Clinton than Trump," Correa told CNN. "I know Hillary, I admire her, I was a student in the US and I did my PhD when Bill Clinton (President) was in. Trump is an enemy of our migrants, why the hell are we going to support him? Sense. CNN reported Monday that after the e-mail dump against Clinton's campaign chairman John Podesta, the US government has voiced concerns about Ecuador that Assange has used its message to support the interference of the Russian elections Afterwards, the embassy interrupted Assange's Internet access and telephone service.
However, in the interview, Correa did not suggest that the US public had inspired this decision, and personally denied a warning from US officials before the 2016 election
The former Ecuadorian leader also said it was "nonsense" that Assange was "the head of the embassy" and downplayed Assange's influence, and the surveillance reports received by CNN described in great detail how Assange's power competed with the Ambassador, and it was alleged that Assange has links with senior officials in Ecuador used to threaten diplomats and guards in the London embassy.
