Yes McCain was alleged to be using the chat portion of online games for what he thought was secret communications.
I was just wasn’t talking about that but about the other Congress critters and the q post about the text threats on POTUS.
Seems like I remember some odd chatter about them using the chat areas in X-Box live or PlayStation or something like that too.
IIRC, terrorists used to do that for secret coded comms about future plans.
