CIA contractor Edward Snowden, who leaked some of America’s most closely guarded secrets, had travelled to India before 2011 but did not report the trip during his background-check process. “The background checkers failed to verify Snowden’s account of a past security violation and his work for the CIA, they didn’t thoroughly probe an apparent trip to India that he had failed to report,” the Wall Street Journal reported, quoting a review after leaks of classified documents by him. During the 2011 routine background check that the National Security Agency contractor needed to keep his security clearance, the checkers didn’t get significant information from anyone who knew him beyond his mother and girlfriend.
