The general counsel of the Defense Department, Jeh Johnson, wrote in a letter transmitted to the author on Thursday that he 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."
