“As for Snowden, I recommend that you contact the Ministry of Justice, this is a matter of criminal investigation, and I will not comment further,” RIA Novosti quotes him.

Earlier, lawyer Anatoly Kucherena, representing the interests of Snowden, said that his client took the oath and received a Russian passport.

On September 26, Russian President Vladimir Putin gave Snowden Russian citizenship.
