at best, superfluous; the case was riddled with prosecutorial and judicial misconduct; their mother was convicted on flimsy evidence to place leverage on her husband, and neither deserved the death penalty." A month later, the brothers published an op-ed in the Los Angeles Times stating that Sobell's confession revealed no detail about the theft of the atom bomb design. They noted that the witness Ruth Greenglass' recently released grand jury testimony said nothing about Ethel Rosenberg's alleged spying activities, for which the government convicted her. The Meeropol brothers have endorsed the conclusions of Walter Schneir, in his posthumously published book Final Verdict, that Greenglass's version of events was concocted – that Julius Rosenberg had been given notice of termination by the KGB in early 1945, and thus was out of the espionage loop when a cross-section drawing of an implosion-type atomic bomb (exhibit 8 at the Rosenberg Trial) was passed to the Soviets. Schneir said that David and / or Ruth Greenglass turned that drawing and descriptive material over to a KGB agent in December 1945 – not, as testified at the trial, to Julius Rosenberg in September 1945. In 2015 after the death of David Greenglass, his secret grand jury testimony was released. Claiming that that testimony supported their view that their mother was not an espionage agent (twice Greenglass under oath before the Grand Jury asserted he had never spoken with his sister about any of his espionage activities with Julius Rosenberg or Ruth Greenglass) the brothers Meeropol wrote an op-ed in The New York Times'' demanding that the US government exonerate their mother. On September 28, 2015, the date that would have been Ethel Rosenberg's 100th birthday, the brothers and eight members of their extended families (including one great-grandchild of the Rosenbergs) gathered on the steps of New York's City Hall to receive two proclamations – one by 13 City Council members and one by the Borough President of Manhattan honoring Ethel Rosenberg and decrying her reputedly false conviction and execution. Meeropol and his brother Robert appeared on the CBS news magazine show 60 Minutes in the fall of 2016 arguing that their mother deserved exoneration because of the recent release of grand jury testimony by her chief accuser, David Greenglass, which directly contradicted his trial testimony against her. They submitted requests to President Obama for a proclamation to in effect nullify the original jury verdict because
