WASHINGTON - The Pentagon's top lawyer has informed the former Navy SEAL who authored a forthcoming book describing details of the raid that killed Osama bin Laden that he violated agreements to not divulge military secrets and that as a result the Pentagon is considering taking legal action against him.

Mark Owen wrote the tell-all, which is causing a buzz even before it hits the nation's book shelves.  

The general counsel of the Defense Department, Jeh Johnson, wrote in a letter transmitted to the author on Thursday that Owen had signed two nondisclosure agreements with the Navy in 2007 that obliged him to "never divulge" classified information.

Johnson said that after reviewing a copy of the book, "No Easy Day," the Pentagon concluded that the author is in "material breach and violation" of the agreements.

Johnson said the department is considering pursuing against him "all remedies legally available to us."

The book is scheduled to be out September 4.
