Morton Sobell, convicted with the Rosenbergs, still lives at 101.

[TomSea]

Morton Sobell (born April 11, 1917) is an American former engineer with General Electric and Reeves Electronics who worked on military and government contracts and who was subsequently found guilty of spying for the Soviets as a part of a ring that included Julius Rosenberg and others. Sobell was tried and convicted of espionage in 1951 and sentenced to 30 years in prison. He was released in 1969 after spending 17 years and 9 months in prison.

Wall Street Journal published an interview with him in June: https://www.wsj.com/articles/i-bet-on-the-wrong-horse-says-an-unrepentant-101-year-old-spy-1529707003

I had no idea of this person.

Damn Russian Collusion. Someone better call Stupid Bobby to look and see if this guy was in contact with Trump.

The final nail in the coffin, so to speak, was the testimony of Morton Sobell in 2008.  Sobell had been the Rosenbergs’ co-defendant and had received a 30-year sentence.  He had, like the Rosenbergs, always maintained his innocence, but at the age of 91 he admitted that he and Julius Rosenberg had, in fact, been Soviet agents.
