Federal law is primarily adopted by which entity?

Federal law is primarily adopted by the U.S. Congress. This legislative body, composed of two chambers—the House of Representatives and the Senate—has the authority to create, amend, and repeal laws at the federal level. Established by the Constitution, Congress is responsible for enacting legislation that applies across all states, addressing issues that affect the country as a whole.

While state legislatures and local governments may create laws applicable within their respective jurisdictions, they do not have the power to enact federal laws. Administrative agencies can implement and enforce laws enacted by Congress, but they do so within the framework established by the legislative body and do not originate those laws themselves. Therefore, understanding that the U.S. Congress is the key player in crafting federal legislation is vital for grasping how the legal and regulatory framework operates at the national level.
