You'll recall the 17 joint intelligence agency report on the Russian hacking of Hillary Clinton's smartphone. They used a key logger to do so. When I'm calling the offices of Democratic Senators I am sure to mention that to their staffers. It has helped to break the ice with them on the issue of getting the troops MFA/OOBA on their mobile devices. Every call so far has been received well. Staff states they are printing the WSJ article, underlining the Lt. Col's tracking/geo-locating concern & will themselves get it to their Senator or the senior staffer who handles military/intelligence matters.
