Founders of the Committee were Frank Gannett, Amos Pinchot and Edward Rumely. The organization enjoyed considerable success in opposing the Bill, also because of large mailing list campaign targeted at legal professionals.
Pinchot would later lead an America First chapter in New York City, although the committee itself was silent on the foreign policies of Roosevelt, and included many interventionists as its members. Gannett would become a presidential candidate in 1939.
Other people associated with the Committee were congressmen Samuel B. Pettengill, John M. Pratt, and Ralph W. Gwinn, John T. Flynn and Robert E. Wood.
The Committee would be thrice investigated by Congress for suspected lobbying activities. Most notably, Rumely would be indicted for Contempt of Congress, twice. In 1946, he would be acquitted in the second Congressional investigation. In 1953, he would be cleared in the third Congressional investigation, a case he pleaded all the way the United States Supreme Court on appeal.
