In a media interview, Moreno said he had received written assurances from Britain that Assange could leave the building safely. Assange has published troves of sensitive material, going back to military documents obtained by Chelsea Manning in 2010.
He noted that Assange still faces jail time in the United Kingdom for violating bail terms when he sought asylum to avoid being extradited to Sweden, where authorities wanted to question him as part of a sexual assault investigation.
Britain has provided enough guarantees that Julian Assange will not be extradited to any country where he would face the death penalty if he leaves the Ecuadorian embassy in London, according to Ecuadorian President Lenin Moreno.

In July, Mueller charged 12 Russian spies with conspiring to hack the Democratic National Committee computers, stealing and publishing data in an effort to sway the election.
Assange's statement doesn't preclude extradition on non-capital charges, however, and on November 15, US federal prosecutors accidentally revealed that Assange had been fingered under seal in the ongoing investigation into Russian meddling in the 2016 USA presidential election. Transmitting defense information to be used for injuring the United States can be punishable by death.
