They made the revelation during an interview on ABC's This Week. They declined to reveal Snowden's whereabouts in Russia, as well as the schedule of their visit. But Fein said the trip would happen "very soon."

　　Anatoly Kucherena, Snowden's lawyer in Russia, said last week he had sent Lon Snowden the required invitation to visit Russia, a step toward securing a visa. He said he hoped a visit would happen in the coming days.

　　Snowden was stranded at Moscow's Sheremetyevo airport for six weeks after Washington revoked his passport. He faces espionage charges in the United States after disclosing a classified intelligence surveillance project code-named PRISM.

　　On Aug. 1, Russia granted him a year-long asylum, allowing him to quietly slip out of the airport.
