Snowden is trying to avoid an extradition order to the U.S. where he faces espionage charges after disclosing classified information detailing the NSA’s secret surveillance programs.  

He fled to Moscow airport, where he has been holed up in the transit zone for weeks. While Snowden has received asylum from several Latin American countries, he needs the permission of Russian authorities to travel there after the U.S. revoked his passport.

Kucherena said earlier this week that Snowden had formally applied for temporary asylum in Russia and would honor President Vladimir Putin’s request to stop releasing information damaging to the U.S.

The dispute though threatens to sour U.S.-Russia relations, with the White House suggesting Tuesday that Obama could snub Putin and cancel planed one-on-one talks in Russia in September.
