That memo shows no such thing. The persistence of this story is crazy. The article even links to the ample evidence of her participation. Just because she was physically unable to meet assets or whatever "work" means, doesn't mean she isn't guilty of espionage.

This is the sad story of children unable to come to terms with the fact that their parents were Soviet spies.
