Navy Seal writes book on Osama Bin Laden raid – Barbara Starr on safety concerns for other Seal team members

(CNN) - A book company said Wednesday that it will release on September 11 a firsthand account of the raid that killed al Qaeda leader Osama bin Laden.

Christine Ball, director of marketing and publicity for Dutton, a subsidiary of Penguin Group USA, said the book was written by a Navy SEAL under a pen name.

The book is entitled "No Easy Day: The Firsthand Account of the Mission That Killed Osama bin Laden."

A Department of Defense official said the SEAL is no longer on active duty.

U.S. Special Operations Command has not reviewed the book or approved it, the official said. Officials only recently became aware the former SEAL was writing a book but were told it encompasses more than just the raid and includes vignettes from training and other missions.

This morning on "Early Start," CNN's Barbara Starr looks at how the Pentagon was caught off guard by the book, and publicity concerns around the safety of other operatives involved in the operation.
