First as special assistant to the Secretary for the Tax Division, and later as the Department's General Counsel, Acting Secretary of the Treasury for Foreign Funds Control, and the Roosevelt Administration's chief spokesperson on tax matters on Capitol Hill, Paul convinced Morgenthau to embrace Keynesian principles and to consider taxation as a vehicle for social progress.
Paul is credited with modernizing the Internal Revenue Code and persuading Congress to enact the payroll withholding tax.
[4] Entitled "Report to the Secretary on the Acquiescence of This Government in the Murder of the Jews", written by Josiah DuBois, the document was an indictment of the U.S. State Department's diplomatic, military, and immigration policies.
Among other things, the Report narrated the State Department's inaction and in some instances active opposition to the release of funds for the rescue of Jews in Romania and occupied France, and condemned immigration policies that closed American doors to Jewish refugees from countries then engaged in their systematic slaughter.
