Buckwheat - who passed in the intel then? Or are you saying it coulod have been all three - of you don’t know?

Rosenberg's were framed and executed innocent scapegoats for passing atomic secrets to the soviets?

Maj. George Racey Jordan made claims regarding what may be the most explosive information regarding the prelude to the Cold War - he claimed that Harry Hopkins, during WWII, had arranged for the transfer of atomic weapons materials to the Soviets. Wikipedia cites a hagiographer of Harry Hopkins to counter this claim as follows - "Historian David L. Roll refutes Jordan's claims of meeting with Hopkins in Washington regarding uranium shipments at a time when Hopkins was in intensive care at the Mayo Clinic in Minnesota. Roll notes that in 1963 the FBI concluded that Jordan's allegations could not be substantiated. Roll says Jordan "either lied for publicity and profit or was delusional."": https://en.wikipedia.org/w/index.php?title=George_Racey_Jordan&diff=640752912&oldid=603886296#Congressional_testimony
However, much refutation of Roll occurs at the bottom of this item: http://www.dcdave.com/article5/140121.htm
The confusion surrounding these apparent discrepancies was resolved in the hearings regarding his allegations, pp. 1153-1174: https://archive.org/details/hearingsregardin1950unit
George Racey Jordan cites corroborative evidence on chapters 13-15 of his book.
Another item of corroboration is from Antony Sutton, in "Western Technology and Soviet Economic Development, Vol. II", p. 167 in a footnote and in "Western Technology and Soviet Economic Development, Vol. III", p. 3 in a footnote. These books are available on the internet.
Most important, however, is the following -
See also a receipt for a 1943 shipment of uranium oxide and uranium nitrate ordered by Harry Hopkins to be sent to the Soviet Union. It appears on p. 468 of "The Venona Secrets, Exposing Soviet Espionage and America's Traitors" (Regnery History (October 2001)) by Herbert Romerstein and Eric Breindel. It corroborates the testimony of Maj. George Racey Jordan, who was witness to these shipments.
Incidentally, in 1980, James Roosevelt, the son of Franklin Roosevelt, wrote a "novel", "A Family Matter", which mentioned how his father made "a bold secret decision... to share the results of the Manhattan Project with the Soviet Union," in 1943 and 1944.
