Which agency is responsible for supervising compliance with campaign contributions?

The agency responsible for supervising compliance with campaign contributions is the Election Law Enforcement Commission. This New Jersey state agency oversees the disclosure of campaign finances and ensures candidates and political organizations adhere to the laws regarding campaign contributions and expenditures. Its functions include monitoring filings of campaign finance reports, enforcing compliance with regulations, and providing guidance for both candidates and contributors on the state's campaign finance laws.

While the Federal Election Commission oversees campaign contributions at the federal level, the State Election Board typically focuses on the administration of state elections rather than specifically on finance compliance. The Campaign Finance Office, while it may relate to campaign finance, is not the formal agency designated in New Jersey for overseeing compliance specifically. Thus, the Election Law Enforcement Commission is the correct answer as it directly handles the enforcement and regulation of campaign finance practices within the state.
