Former US National Security Agency (NSA) contractor Edward Snowden has criticized WikiLeaks, a seemingly fellow whistleblower, on Twitter for failing to provide “modest curation.”

WikiLeaks, which helped Snowden secure asylum in Russia, didn’t take long to reply, apparently implying that the whistleblower might be trying to find ways to mend ties with Washington.

While he credited WikiLeaks for its role in what he called “democratizing” information, the former government contractor, who himself released a trove of secret NSA documents, suggested at least some “curation” wouldn’t hurt when making documents public.

Democratizing information has never been more vital, and @Wikileaks has helped. But their hostility to even modest curation is a mistake. — Edward Snowden (@Snowden) July 28, 2016

Snowden’s observation comes just days after the pro-transparency publisher released voicemails from top Democratic officials and internal emails of the Democratic National Committee (DNC) that had been obtained in a hack. WikiLeaks founder Julian Assange has promised there is “a lot more material” to come.

In response, WikiLeaks hinted that the NSA whistleblower’s criticism might be a ploy to “earn a pardon” from US Democratic presidential nominee Hillary Clinton. Snowden is currently living in exile in Russia.
