and come back to the United States."
"The bottom line is this is a man who has betrayed his country, who is sitting in Russia, an authoritarian country where he has taken refuge," Kerry told the CBS "This Morning" program on Wednesday.
Snowden made clear he would not return to the United States and hope for the best. He said he would not simply "walk into a jail cell," and that if his one-year asylum in Russia, which expires on Aug. 1, "looks like it's going to run out, then of course I would apply for an extension."
The Guardian newspaper quoted Ben Wizner, a lawyer for the American Civil Liberties Union and legal adviser to Snowden, responding to Kerry's comments. Wizner said it would be impossible for Snowdon to argue that his disclosures had served the common good if he returned home to face the current Espionage Act charges.
He also said Snowden would run the risk of facing numerous additional charges for each document that has been published.
"The exposure that he faces is virtually unlimited under this," Wizner said.
In one odd moment in the NBC interview, Snowden expressed sympathy for working-level NSA employees who have been castigated as a result of his leaks.
"People have demonized the NSA to a point that's too extreme," he said, adding that the problem is with senior-level officials who expand their surveillance powers without public debate.
