No Easy Day: Osama bin Laden raid tell-all contains classified info, Pentagon says (VIDEO)

A highly-anticipated firsthand account of the raid that killed Osama bin Laden was released Tuesday, to the chagrin of the Defense Department, CNN reported.

In a review, the Los Angeles Times called the book — which has topped Amazon's best-seller list for two weeks from pre-orders alone — "brisk and compelling," and "an important historic document."

But the Pentagon has taken issue with the book's publication, claiming that author and former Navy SEAL Matt Bissonnette, who wrote the book under the pseudonym Mark Owen, included classified information in the text, CBS and the Associated Press reported. Bissonnette also did not submit the book for a required review prior to publication, according to Pentagon press secretary George Little, as cited by news outlets. Bissonnette's lawyer denied that his client had breached any agreements, according to the AP.

Reuters, which obtained an advance copy of the book, reported that Bissonnette "decided to do the book because details of the raid that were being leaked by others in government were wrong."

But Bissonnette's account won't be the only one publicly available for long, according to Reuters. "A follow-up e-book called 'No Easy Op'" is said to be in the works, authored by special operations forces who will discuss the politics behind the raid to kill Osama bin Laden, Reuters reported.

The book's release was initially planned for Sept. 11, to commemorate the 9/11 attacks, according to the Huffington Post. The publisher moved the date up a week in response to "overwhelming excitement," the AP reported.

In spite of the pre-election timing, in an interview with CBS, Bissonnette said that his book does not have a political agenda.

"This book is not political whatsoever," Bissonnette said during an interview with 60 minutes, slowly shaking his head. Bissonnette was identified by CNN as the interviewee, though CBS used his pen name, Mark Owen.
