United States Federal Law refers to the body of laws created by the federal government of the United States. These laws are established by the U.S. Congress, which consists of two chambers: the House of Representatives and the Senate. Federal laws apply to all states and can cover a wide range of issues, including civil rights, immigration, and taxation. Federal laws are enforced by various agencies, such as the Federal Bureau of Investigation (FBI) and the Department of Justice. When conflicts arise between state and federal laws, federal law generally takes precedence due to the Supremacy Clause in the U.S. Constitution.
