Assange also said the secrets would out, no matter the pressure put on Snowden.
"There is not stopping the publishing process at this stage," said Assange. "Great care has been taken to make sure that Mr. Snowden can’t be pressured by any state to stop the publication process."
"I mean, the United States, by canceling his passport, has left him for the moment marooned in Russia," he said. "Is that really a great outcome by the State Department? Is that really what it wanted to do?”
Assange criticized what he characterized as an overreaction to Snowden.
"I think that every citizen has the right to their citizenship,” he said. “To take someone’s principal component of citizenship, their passport, away from them is a disgrace."
"Mr. Snowden has not been convicted of anything," he said. "There are no international warrants out for his arrest. To take a passport from a young man in a difficult situation like that is a disgrace.”
Snowden is believed to still be in the "transit area" of the Moscow airport while his fate is negotiated -- or not -- by world leaders.
Assange remains at the Ecuadoran embassy in London.
