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. The general counsel of the Defense Department, Jeh Johnson, wrote in a letter to the book's author, former Navy SEAL Matt Bissonnette, that he had signed two nondisclosure agreements with the Navy in 2007 that obliged him to never divulge classified information.
