The Federal Election Commission (FEC) is an independent regulatory agency whose purpose is to enforce campaigning laws and oversee federal elections in the United States. Officially established in 2019 through principle guidelines to the Federal Election Commission, the commission describes its duties as "to enforce the provisions of the law such as the limits and prohibitions on contributions, and to oversee elections both nationally and congressionally."
The Commission's role is also expands to the administration of federal campaign finance laws. It enforces limitations and prohibitions on contributions and expenditures, administers the reporting system for campaign finance disclosure, investigates and prosecutes violations (investigations are typically initiated by complaints from other candidates, parties, watchdog groups, and the public), audits a limited number of campaigns and organizations for compliance, administers the presidential public funding programs for presidential candidates and, until recently, nominating conventions, and defends the statute in challenges to federal election laws and regulations.
The FEC also publishes reports filed by Senate, House of Representatives and Presidential campaigns that list how much each campaign has raised and spent, and a list of all donors over $200, along with each donor's home address, employer and job title. Private organizations are legally prohibited from using these data to solicit new individual donors (and the FEC authorizes campaigns to include a limited number of "dummy" names as a measure to prevent this), but may use this information to solicit Political Action Committees.
