Regarding the Pelosi laptop.
We saw with Hillary that she got around national security measures by installing a homebrew email server. She also insisted on using an insecure phone (Blackberry?) and whenever it was removed and replaced she simply got another to her liking. She also carried her phone into secure areas in breech of the rules. When you're arrogant, security measures don't apply.
Pelosi was no doubt issued with a congressional device. It would have endpoint protection installed, with file upload to the cloud. Hard drive encrypted, ports disabled and probably a tracking device which would call the mothership the moment it was connected to the internet. Only a total idiot would plan a coup on such a device. Take a leaf out of Hillary's book. Bring in your own laptop. For the sake of security, disable wifi, never plug it into a network and don't update the software. Such a device would have NO backup to cloud. It would also be more or less hack proof.
If such a laptop were stolen, then Pelosi's plans would indeed be comp'd.
