This bill amends federal election law to prevent foreign money from influencing U.S. elections by extending restrictions on foreign nationals to include domestic businesses that are foreign-controlled or foreign-influenced. Currently, the law bans direct contributions from foreign nationals, but this legislation closes loopholes by prohibiting contributions from any U.S. business in which a foreign entity owns 50 percent or more of the company, or owns as little as 1 percent if that foreign owner can control the company's decisions about U.S. elections. The bill requires business leaders to certify under penalty of perjury within seven days of making campaign contributions that their company does not have prohibited foreign ownership or control, and political committees must keep records showing they received this certification before using the funds. The changes take effect 180 days after the bill becomes law, regardless of whether the Federal Election Commission has finished writing detailed regulations. The bill also extends foreign money bans to contributions affecting state and local ballot measures and requires corporate political action committees to certify that all fund managers are U.S. citizens and that no foreign nationals participate in their spending decisions.
