Snowden's father said that he was confident Putin would not change his mind and send his son back to the United States to face espionage charges.
"President Vladimir Putin has stood firm. I respect strength and I respect courage," Snowden said. "He has stood firm against the face of intense pressure from our government and I have to believe that he will continue to stand firm."
Remind that, Mr. Snowden is accused of leaking classified information. Documents disclosed by Snowden revealed that the NSA has access to vast amounts of internet data from large companies such as Facebook and Google, under a government programme known as Prism. They also showed that the government had worked through the secret Foreign Intelligence Surveillance Court to gather so-called metadata – such as the time, duration and telephone numbers on calls carried by service providers such as Verizon.
