NSA Leak Inquiry to Explore Whether Snowden Had China Tie

Counterintelligence and criminal investigators are examining whether Edward Snowden, the technology contractor who leaked details about classified U.S. spy programs, might have been recruited or exploited by China.

To pursue that question, investigators will use the very surveillance tools revealed by Snowden to probe his own phone calls and online communications to see whether he’s had any contact with Chinese or other foreign agents, as well as whether security officials missed any signs that he might be a security risk, said two U.S. officials briefed on the matter.
