Weinstone was elected as a delegate to the founding convention of the Communist Party of America, called to order in Chicago on September 1, 1919.

Weinstone traveled at that time without portfolio and was reported by high-ranking party member and FBI informant Morris Childs to have been considering seeking employment and staying in the USSR on a long-term basis.
