Julian Assange was able to turn the Ecuadorian embassy in London into a command center for meddling in the 2016 US presidential election, a report said Monday.

Documents obtained by CNN detail how the WikiLeaks founder received in-person deliveries, potentially containing hacked materials from Russian operatives during sometimes hour-long meetings at the embassy.

The hundreds of pages of surveillance reports and visitor logs were compiled by UC Global, a private Spanish security firm hired by the Ecuadorian government.

The information supports the suggestion raised by Special Counsel Robert Mueller in his report that WikiLeaks helped the Russians undermine the US election.

The reports show that Assange met with Russians and “world-class hackers” before critical leaks.

He also got his hands on computer and network hardware updates to help with the transfer of massive encrypted files from Russian operatives, according to the documents.

The security logs said that Assange personally managed some of the document releases “directly from the embassy.”

After the election, the security company assessed Assange’s allegiance and found that there was “no doubt that there is evidence” that the Australia native has ties to Russian intelligence agencies.

Assange has always denied working for the Kremlin and insists his source for the leaks “is not the Russian government and is not a state party.”

In April, the US unsealed a computer hacking indictment against Assange for his role in helping Chelsea Manning infiltrate Pentagon computers.

Assange is serving a one-year prison sentence in London for skipping bail in the UK and is fighting extradition to the US.

A dozen Russian intelligence officers were indicted in 2018 as part of Mueller’s probe for working with WikiLeaks and hacking the Democratic National Committee and Hillary Clinton’s 2016 presidential campaign.
