A woman started (from his perspective) stalking him, emailing him under false pretenses, phoning him, calling his son, and then showing up at his house in person. He called the cops to keep this stalker (again, from his perspective) away from his house. She yelled some questions at him from a distance and he might have thought she was asking about DoD work. "No longer involved and cannot discuss" is a reasonable answer. As well as: Don't come back.
I asked Newsweek's editor in chief a few hours ago about any recording: https://twitter.com/declanm/status/441713108763951104
No response.
