If any of this was done on work computers [remember, Signal, Telegram, Whatsap, Sessions, etc all have desktop applications as well] the IT departments have access to all the discussions and conversations to all the Signal Groups.

It's been exposed that the Lt Gov MN was one of the admins of one of the organizing Signal groups being used against ICE/Federal Agents activities. Individuals who work at Banks, government agencies (national databases for licence plate identification), and private companies such as hotels, etc.

Any work done on a company/government computer is not secure no matter what that individual thinks. Conversations, logs, membership lists, etc. It's an IT admin's dream.

and remember, not all who work in IT are on the side of the communists
