A newly declassified FBI document, reported on Thursday by JustTheNews.com, reveals the name of Ms. Lokhova, which was redacted from the January communication. Her name makes it clear the FBI was describing a 2014 dinner at Cambridge, where Ms. Lokhova studied Russian history and Mr. Flynn, then-director of the Defense Intelligence Agency, spoke. It is also clear the CHS is Mr. Halper, at the time a Cambridge professor, because the FBI document tells of other known missions for the spy, such as reaching out to Trump campaign official Sam Clovis. The document also mentions agent Stephen M. Somma, Mr. Halper’s handler.
