At the urging of Trotsky and James P. Cannon James was invited to tour the United States by the leadership of the Socialist Workers' Party in October 1938. He kicked off his national speaking tour on the 6th of January 1939 in Philadelphia. Constance Webb who later became James' second wife attended one of his lectures in Los Angeles and reflected on it in her memoir. She noted hearing him speak alongside Winston Churchill and Franklin Delano Roosevelt as three great orators. James stayed in the United States until he was deported in 1953. By 1940 he had begun to doubt Trotsky's view of the Soviet Union as a degenerated workers' state. He left the SWP along with Max Shachtman who formed the Workers' Party. Within the WP James formed the Johnson, Forest Tendency with Raya Dunayevskaya and Grace Lee Boggs to spread their views within the new party. As J. R. Johnson James wrote the column The Negro Question for Socialist Appeal which was later renamed The Militant. While within the WP the views of the Johnson, Forest Tendency underwent considerable development. By the end of the Second World War they had definitively rejected Trotsky's theory of Russia as a degenerated workers' state. Instead they classified it as state capitalist. Unlike Tony Cliff the Johnson, Forest Tendency focused increasingly on liberation movements of oppressed minorities. After a few short months as an independent group during which they published a great deal of material in 1947 the Johnson, Forest Tendency joined the SWP. In 1955 after James had left for Britain about half the membership of the Committee withdrew under the leadership of Raya Dunayevskaya to form a separate tendency of Marxist humanism.
