This legislation establishes a clear policy of strict political neutrality for the United States in the internal electoral processes of foreign countries. It explicitly prohibits the use of U.S. diplomatic facilities, including embassies, consulates, other diplomatic posts, and official residences, for hosting fundraising events for foreign political parties or candidates. This prohibition extends to the obligation or expenditure of both federal funds and the personal funds of U.S. Ambassadors or other officials for such purposes. The bill defines a "fundraising event" broadly to include any event intended to raise funds for, or on behalf of, a political party or candidate, including by facilitating contact between potential donors and political entities. It amends existing statutes, such as the Foreign Service Act of 1980 and the State Department Basic Authorities Act of 1956, to reinforce these prohibitions on expenditures for official receptions or activities intended for foreign political fundraising. Furthermore, the Secretary of State is mandated to revise the Department of State Standardized Regulations (DSSR) and the Foreign Affairs Manual (FAM) to reflect these new prohibitions and discourage any activity that could be perceived as promoting the financial interest of a foreign political party or candidate. The Secretary must certify these revisions to Congress within 90 days of the Act's enactment.
