This bill strengthens restrictions on foreign money in U.S. elections by expanding what types of election activities foreign nationals are prohibited from funding, including voter registration, ballot collection, get-out-the-vote efforts, and election administration. It also makes it illegal to knowingly help someone else violate these foreign funding bans and treats indirect contributions funneled through intermediaries the same as direct foreign donations. The legislation requires political committees, parties, and those making independent expenditures to certify under penalty of perjury that they comply with foreign funding prohibitions in their official reports to the Federal Election Commission. Additionally, the bill protects donor privacy by generally prohibiting federal agencies from collecting or publicly releasing information that identifies donors to tax-exempt organizations, with limited exceptions for the IRS, Congress, and the FEC acting under existing legal authority, and makes unauthorized disclosure of such donor information a felony punishable by up to five years in prison and fines up to $250,000. These provisions take effect upon enactment of the bill.
