Edward Snowden leaked as many as 200,000 classified U.S. documents to the media this year, according to NSA chief Gen. Keith Alexander.
Alexander made the comments after a speech in Baltimore last month, Reuters reported Thursday. The news service obtained a copy of the October event's transcript from the National Security Agency.
"I wish there was a way to prevent it. Snowden has shared somewhere between 50 [thousand] and 200,000 documents with reporters. These will continue to come out," Alexander said, according to the report.
