“It’s inconceivable to me that people would not use the classified channels that the government has spent so much time and effort and money over decades trying to make as uncompromisable as they can. And whether it’s secure videos, secure telephones, secure text or email kinds of things, the channels are there.
It’s not like they don’t exist. Why would you ever not use them?”— Former Trump national security adviser John Bolton, quoted by WBUR.
