NSA whistleblower Edward Snowden has been condemned by US politicians and intelligence chiefs and threatened with prosecution, The Guardian reports.
A spokesman for the director of national intelligence, James Clapper, said US intelligence was assessing the damage caused by his disclosures, and that his case had been referred to the justice department.
"Any person who has a security clearance knows that he or she has an obligation to protect classified information and abide by the law."
Peter King, chairman of the House homeland security subcommittee said:
"If Edward Snowden did in fact leak the NSA data as he claims, the United States government must prosecute him to the fullest extent of the law and begin extradition proceedings at the earliest date."
"It's like a thief shouting stop thief," that's how a leading Chinese expert described the fallout from the NSA spying revelations.
The revelation of the Prism intelligence-gathering program will undermine the US' moral authority to deal with China over cyber espionage.
America's top intelligence official has called Edward Snowden's actions a "violation of sacred trust."
