1947 he became chairman of the United States House Committee on Foreign Affairs and of the Herter Committee. With a Democratic president (Harry S. Truman) and a Republican Congress, and with the influence of economic aid in foreign policy, the chairmanship was a powerful post. Eaton's leadership was at times strongly challenged by the neo-isolationist group in the House, but he achieved the passage of every piece of legislation that he sponsored, including continuation of United Nations Relief and Rehabilitation Administration (UNRRA), a program of aid to Greece and Turkey (the Truman Doctrine), and the Marshall Plan. The opposition to these programs centered in the House and Eaton was their chief defender. The passage of the Marshall Plan was a high point in Eaton's political career. President Truman gave testimony in his memoirs to Eaton for his bipartisan support of American foreign policy. Twenty days after his retirement from Congress, Eaton died in Washington, D.C., and was interred in Hillside Cemetery in Scotch Plains, New Jersey. Evangelism In 1904, Eaton's commitment to evangelism got him arrested on the streets of Cleveland, Ohio, for persistently ignoring by-laws prohibiting street preaching. However, he wanted to extend his ministry beyond the churches, into which many of the spiritually needy never stepped. At the same time, Eaton was the preacher at Euclid Avenue Baptist Church, situated on Cleveland's "millionaire's row", and as a result he came to the attention of John D. Rockefeller, a summer resident of Cleveland who attended church there. They became lifelong friends, and this connection influenced Eaton's future path. It also influenced that of another well-known Canadian who went on to have an outstanding career in the United States, his nephew, Cyrus S. Eaton. He introduced him to Rockefeller in 1901, when Cyrus was still a university student. Cyrus went on to work for Rockefeller, and eventually become one of Cleveland's first citizens, and one of America's premier industrialists. Charles moved to North Plainfield, New Jersey, in 1909, and started a dairy farm, while at the same time preaching to a prominent New York City Baptist congregation, the Madison Avenue Baptist Church. The area in which he lived separated from North Plainfield in 1926, and the Borough of Watchung, New Jersey, was founded there. He lived there until his death. Journalism Eaton was sociological editor of the Toronto Globe (1896–1901), associate editor of Westminster (1899–1901), special correspondent for The Times,
