WASHINGTON (MCT) — The Pentagon said Tuesday that a former Navy SEAL’s account of the raid that killed Osama bin Laden contains classified information, intensifying a dispute with the author over whether the book harmed national security.

Defense Department spokesman George Little said that an examination of the book, “No Easy Day,” revealed “sensitive and classified information,” and he reiterated that author Matt Bissonnette, writing under the pen name Mark Owen, violated non-disclosure agreements by failing to submit it for government review before it went on sale Tuesday.
