passing campaign finance laws.

Explanation:

Campaign finance legislation is passed by federal government and enforced by the Federal Election Commission which is an independent federal agency. While most campaign financing is funded privately, public funding is available to registering US President candidates. Such legislation also defines who has the ability to make political contributions and what kinds of activities are including in-kind contributions. These laws constrain the sums of money which political campaigns or parties may receive from persons or groups and the aggregate amounts that people or groups may donate.
