National Journal: Napolitano: I Don't Use E-mail. At All. Homeland Security Secretary Janet Napolitano, who is a key player in national cybersecurity efforts, said on Friday she doesn't use e-mail."Don't laugh, but I just don't use e-mail at all," she said during a discussion at a Cybersecurity Summit hosted by National Journal and Government Executive. She didn't explain what communications tools she does use.Given the epidemic levels of abuse and misconduct in several of her major agencies (esp. TSA, CBP, ICE, Secret Service), it's a safe conclusion that she doesn't communicate much, if at all.
