"One of the things I was briefed on very early … was by the CIA records management folks about the use of Signal as a permissible work use," Ratcliffe said during a March 25 Senate Intelligence Committee hearing (see 45:05). "It is. That is a practice that preceded the current administration to the Biden administration."
Sure, but that’s the point-Signal is permitted; it’s the content that matters, not the medium. Ratcliffe's testimony confirms it’s been standard practice across administrations. It’s already approved in IC circles despite your claims it harms national security.
