The new party was subject to many of the same fissures that divided the left in the late 1930s. For a while after the signing of the Molotov–Ribbentrop Pact, CPUSA members within the ALP condemned FDR as a warmonger because of his support for Britain. At one particularly stormy meeting Dubinsky and the other leaders were only able to hold their vote endorsing Roosevelt after moving from room to room and calling the police to arrest those who had disrupted the meeting.
