Just Security: “According to a person familiar with the content of the complaint who spoke to Just Security, when the call was over, senior White House officials pulled the verbatim transcript out of the system that it is traditionally stored on and moved it into a separate system reserved for extremely sensitive/highly compartmented programs.”
“This person said that the call between the two leaders had nothing to do with highly classified programs. But, by moving it into this separate system, the White House could control who could see the transcript: only a very small group of people.”
