In 1995, the US government made public many documents decoded by the Venona project, showing Julius Rosenberg's role as part of a productive ring of spies. For example, a 1944 cable (which gives the name of Ruth Greenglass in clear text) says that Ruth's brother David is being recruited as a spy by his sister (that is, Ethel Rosenberg) and her husband. The cable also makes clear that the sister's husband is involved enough in espionage to have his own code name ("Liberal").
