What enforces laws writes new regulations and sets up new programs?

The enforcement of laws, writing of new regulations, and establishment of new programs are primarily the responsibilities of government agencies and regulatory bodies. These entities operate at various levels—federal, state, and local—depending on the jurisdiction. For example, agencies like the Environmental Protection Agency (EPA) or the Food and Drug Administration (FDA) create regulations to implement laws passed by legislatures. Additionally, executive branches of government, led by elected officials, play a crucial role in shaping policies and initiating new programs.
