U.S. intelligence head wants Snowden, 'accomplices' to return documents

WASHINGTON (Reuters) - The top U.S. intelligence official called on Wednesday for Edward Snowden and journalists who obtained documents the former contractor took without authorization from the National Security Agency to return the materials to authorities.

At a hearing where the heads of five U.S. intelligence agencies ratcheted up rhetoric calling Snowden a "grave threat" to the nation, U.S. Director of National Intelligence James Clapper made comments that appeared to accuse journalists who wrote stories based on Snowden's leaks.
