Defense Secretary Chuck Hagel is ordering military leaders to put a renewed emphasis on moral behavior across the force following a series of ethical lapses that have included cheating scandals among the Navy and Air Force's nuclear missions.
Air Force Secretary Deborah Lee James says the number of nuclear force officers implicated in a proficiency test cheating scandal has grown to 92 out of a force of 500.
A defense official says Defense Secretary Chuck Hagel is going to summon the military's most senior leaders to the Pentagon to discuss serious missteps, leadership lapses and personnel problems in the U.S. nuclear force.
