This woman is a former sub-cabinet political appointee in the Obama Administration's DoD where she dealt with Russian policy matters. At some point in the recent past she was de-briefed (cut off) from access to the various kinds of compartmented information she had been given as a requirement of her job. When that occurred she signed some papers in which she accepted the responsibility to protect the secrecy of that information.
She has recently been on a number of MSNBC shows freely telling people of the extent and success of present and ongoing US SIGINT (COMINT) operations against Russia. She stated on global TV last night and this morning that the US has "very good intelligence on Russia," and that the US successfully intercepts Russian diplomatic communications to include the encrypted telephone communications of Russian diplomats to include the ambassador to the US.
She has stated freely on TV that she and a group of associates from the Obama Administration went to congressional staffers who did not have access to these COMINT products and urged them to seek to gain access to them. This is in basic contradiction to the elementary principle in government security that access to particular products should be dictated from above based on necessity rather than sought from below. In fact an expressed desire to gain greater access is usually something that arouses suspicion about an individual.
It is likely that her disclosure has damaged NSA and FBI success in the COMINT operations that she has compromised to the Russians. pl
