Upon returning to the United States, he and Lovestone, who had also been expelled from the party, formed the Communist Party (Opposition) to further their views. Having expected a majority of American Communists to join them, they were disappointed at only being able to attract a few hundred followers. Wolfe became editor of the CP(O)'s newspaper "Worker's Age" and its chief theorist. Initially, Lovestone and Wolfe hoped to eventually be welcomed back into the Communist movement but when changes in the Comintern's line failed to result in a rapprochement, the CP(O) moved further and further away from communism. Wolfe and Lovestone were sympathisers of Nikolai Bukharin and helped found the International Communist Opposition (also known as the International Right Opposition) which for a time had some influence before petering out.
