Snowden has also fielded inquiries about book and movie projects.

“Any moment that he decides that he wants to be a wealthy person, that route is available to him,” Wizner said, although the U.S. government could also attempt to seize such proceeds.

Wizner declined to discuss where Snowden lives, or how he secured an apartment in a city where such transactions require government involvement — except to indicate that Snowden’s Russian attorney, Anatoly Kucherena, has helped with such arrangements.

Snowden’s relationship with Kucherena, who has close ties to Putin and serves on an FSB advisory board, has fueled speculation that he is working with the Russian government.

McFaul, the former ambassador, raised other questions, including how Snowden has managed to arrange interviews with prominent U.S. journalists — all requiring Russian visas that could not be obtained without FSB approval — but has yet to grant such access any Russian reporters.

“Many Russian journalists are eager to interview him and ask these questions, but so far he has refused,” McFaul said.

Snowden’s critics and supporters do occupy a thin strand of common ground. They agree that Snowden is probably under nearly constant scrutiny by the FSB and lives a life that is constrained by his dependence on the government that granted him asylum.

“When Snowden says that he has ‘no relationship’ with the Russian government, he means that he hasn’t cooperated with their intelligence services in any way and that his asylum isn’t conditioned on cooperation,” Wizner said. “Of course, the Russian government could choose to expel him at any time.”
