THE PENTAGON — The Department of Defense is mandating remedial sexting training for its flag officers following a rash of media reports on sexual misconduct across the military services, according to sources close to Secretary of Defense Ashton Carter.

The sources say this improper conduct has been a persistent problem, and Carter is frustrated that his prior efforts to institute ethics training have proven unsuccessful.

“These guys are clearly going to continue getting caught,” Pentagon Spokesman Peter Cook said, “so now we’re just trying to make their incriminating emails a little less embarrassing.”
