'It’s Time': Whistleblower Edward Snowden Tweets Mysterious Warning

US whistleblower Edward Snowden published a vaguely worded tweet on Wednesday that has aroused curiosity in the Twittersphere.

The post reads like a cryptic rallying call, asking former colleagues of the NSA contractor to contact him, saying "It’s time."

Did you work with me? Have we talked since 2013? Please recontact me securely, or talk to @bartongellman. It's time. https://t.co/AKmgF5AIDJ

The tweet also quotes journalist Barton Gellman, who is currently writing about Snowden’s time working in the intelligence community in order to "tell it truthfully."

In 2013, Snowden leaked a cache of intelligence documents that unveiled the extent of the National Security Agency’s domestic spying apparatus. He currently lives in exile in Russia, and faces charges of espionage and theft of government property in the US.

Gellman isn't the only one interested in Snowden's story. Hollywood director Oliver Stone has released a trailer for his upcoming biopic about the whistleblower. The film should be released later this year.
