...the transcript of the President's call with President Zelenskyy was placed into a computer system managed directly by the National Security Council (NSC) Directorate for Intelligence Programs. This is a standalone computer system reserved for codeword-level intelligence information, such as covert action. According to information I received from White House officials, some officials voiced concerns internally that this would be an abuse of the system and was not consistent with the responsibilities of the Directorate for Intelligence Programs. According to White House officials I spoke with, this was "not the first time" under this Administration that a Presidential transcript was placed into this codeword-level system solely for the purpose of protecting politically sensitive-rather than national security sensitive-information.
