A former member of SEAL Team Six who wrote a best-seller about the raid that killed Osama bin Laden is under criminal investigation for disclosing classified material, NBC News has confirmed. The ongoing probe looks at whether Matthew Bissonnette disclosed classified information in "No Easy Day." According to a source familiar with the author's negotiations over profits from the book, Bissonnette expects that all money will go to Defense Department for violating rules that require former military operators to have their books reviewed by the Pentagon prior to publication.
