Testimony From Rosenberg Brother Released in Famous Spy Case

The brother of Ethel Rosenberg was a star trial witness against his sister and brother-in-law in a sensational Cold War atomic spying case. And according to secret court records unsealed Wednesday, David Greenglass never implicated his sister in an earlier appearance before a grand jury, and said that they had never discussed her role "at all".
The revelation may heighten public suspicion that Ethel Rosenberg was wrongly convicted and executed. The espionage case captivated the country at the height of the McCarthy-era frenzy about Communist allegiances.
Rosenberg and her husband Julius were put to death in 1953 after being convicted of conspiring to pass secrets about the atomic bomb to the Soviet Union. They maintained their innocence until the end.
