Of note, some of the materials presented today by Mueller are WhatsApp messages.
The Official Story is that Pauly Dimwits was backing up his WhatsApp messages to his Apple iCloud account, and Mueller got a warrant to search that. However, there’s also a story today about a Senate staffer being indicted for leaking to a NYTimes reporter (actually, for lying about it to the FBI), and they have the encrypted Whatsapp messages between him and the reporter. Taken together, these two stories make it seem like WhatsApp’s encryption might be a wee bit compromised.
